As with regular Angular components, Angular elements are expected to
have their views update when inputs change.
Previously, Angular Elements views were not updated if the underlying
component used the `OnPush` change detection strategy.
This commit fixes this by calling `markForCheck()` on the component
view's `ChangeDetectorRef`.
NOTE:
This is similar to how `@angular/upgrade` does it:

`ComponentNgElementStrategy` is supposed to call `ngOnChanges()` on the
underlying component instance if available, but not fail if the
component does not have an `ngOnChanges()` method. This works as
expected. However, the test used to verify that was invalid; i.e. the
test would pass even if `ComponentNgElementStrategy` would try to call
`ngOnChanges()` on a component without such a method.
This commit replaces the invalid test with a new one that correctly
verifies that `ComponentNgElementStrategy` does not try to call
`ngOnChanges()`.

In ViewEngine, SelfSkip would navigate up the tree to get tokens from
the parent node, skipping the child. This restores that functionality in
Ivy. In ViewEngine, if a special token (e.g. ElementRef) was not found
in the NodeInjector tree, the ModuleInjector was also used to lookup
that token. While special tokens like ElementRef make sense only in a
context of a NodeInjector, we preserved ViewEngine logic for now to
avoid breaking changes.
We identified 4 scenarios related to @SkipSelf and special tokens where
ViewEngine behavior was incorrect and is likely due to bugs. In Ivy this
is implemented to provide a more intuitive API. The list of scenarios
can be found below.
1. When Injector is used in combination with @Host and @SkipSelf on the
first Component within a module and the injector is defined in the
module, ViewEngine will get the injector from the module. In Ivy, it
does not do this and throws instead.
2. When retrieving a @ViewContainerRef while @SkipSelf and @Host are
present, in ViewEngine, it throws an exception. In Ivy it returns the
host ViewContainerRef.
3. When retrieving a @ViewContainerRef on an embedded view and @SkipSelf
is present, in ViewEngine, the ref is null. In Ivy it returns the parent
ViewContainerRef.
4. When utilizing viewProviders and providers, a child component that is
nested within a parent component that has @SkipSelf on a viewProvider
value, if that provider is provided by the parent component's
viewProviders and providers, ViewEngine will return that parent's
viewProviders value, which violates how viewProviders' visibility should
work. In Ivy, it retrieves the value from providers, as it should.
These discrepancies all behave as they should in Ivy and are likely bugs
in ViewEngine.

There is a compiler transform that downlevels Angular class decorators
to static properties so that metadata is available for JIT compilation.

Tokenized text node may have leading whitespace skipped from their

interpolated blocks, resulting in placeholder nodes whose source-spans

the source-span of placeholders, so that they are accurate.

The lexer is able to skip leading trivia in the `start` location of tokens.
This makes the source-span more friendly since things like elements
appear to begin at the start of the opening tag, rather than at the
start of any leading whitespace, which could include newlines.
But some tooling requires the full source-span to be available, such
as when tokenizing a text span into an Angular expression.

When a class with a custom decorator is transpiled to ES5, it looks something like this:
```
var SomeClass = (function() {
function SomeClass() {...};
var SomeClass_1 = __decorate([Decorator()], SomeClass);
SomeClass = SomeClass_1;
return SomeClass;
})();
```
The problem is that if the class also has an Angular decorator that refers to the class itself
(e.g. `{provide: someToken, useClass: SomeClass}`), the generated `setClassMetadata` code will
be emitted after the IIFE, but will still refer to the intermediate `SomeClass_1` variable from
inside the IIFE. This happens, because we generate the `setClassMetadata` call directly from
the source AST which contains identifiers that TS will rename when it emits the ES5 code.
These changes resolve the issue by looking through the metadata AST and cloning any `Identifier`
that is referring to the class. Since TS doesn't have references to the clone, it won't rename
it when transpiling to ES5.

Currently expressions `$event.foo()` and `this.$event.foo()`, as well as `$any(foo)` and
`this.$any(foo)`, are treated as the same expression by the compiler, because `this` is considered
the same implicit receiver as when the receiver is omitted. This introduces the following issues:
1. Any time something called `$any` is used, it'll be stripped away, leaving only the first parameter.
2. If something called `$event` is used anywhere in a template, it'll be preserved as `$event`,
rather than being rewritten to `ctx.$event`, causing the value to undefined at runtime. This
applies to listener, property and text bindings.
These changes resolve the first issue and part of the second one by preserving anything that
is accessed through `this`, even if it's one of the "special" ones like `$any` or `$event`.
Furthermore, these changes only expose the `$event` global variable inside event listeners,

To support recovery of malformed binding property names like `([a)`,
`[a`, or `()`, the binding parser needs to be more permissive w.r.t. the
kinds of bindings it can detect. This is difficult to do maintainably
with a regex, but is trivial with a "hand-rolled" string parser. This
commit refactors render3's binding attribute parsing to use this method
for multi-delimited bindings (namely via the `()`, `[]`, and `[()]`)
syntax, making the way recovery of malformed bindings in a future patch.
Note that we can keep using a regex for prefix-only binding syntax
(e.g. `bind-`, `ref-`) because validation of the binding is complete
once we have matched the prefix, and the only thing left to do is check
that the binding identifier is non-empty, which is trivial.

Fix an issue that `markDirty()` will not trigger change detection.
The case is for example we have the following component.
```
export class AppComponent implements OnInit {
constructor(private router: Router) {}
ngOnInit() {
this.router.events
.pipe(filter((e) => e instanceof NavigationEnd))
.subscribe(() => ɵmarkDirty(this));
}
}
export class CounterComponent implements OnInit, OnDestroy {
ngOnInit() {
this.countSubject.pipe(takeUntil(this.destroy)).subscribe((count) => {
this.count = count;
ɵmarkDirty(this);
});
}
```
Then the app navigate from `AppComponent` to `CounterComponent`,
so there are 2 `markDirty()` call at in a row.
The `1st` call is from `AppComponent` when router changed, the
`2nd` call is from `CounterComponent.ngOnInit()`.
And the `markDirty()->scheduleTick()` code look like this
```
function scheduleTick(rootContext, flags) {
const nothingScheduled = rootContext.flags === 0 /* Empty */;
rootContext.flags |= flags;
if (nothingScheduled && rootContext.clean == _CLEAN_PROMISE) {
rootContext.schedule(() => {
...
if (rootContext.flags & RootContextFlags.DetectChanges)
rootContext.flags &= ~RootContextFlags.DetectChanges;
tickContext();
rootContext.clean = _CLEAN_PROMISE;
...
});
```
So in this case, the `1st` markDirty() will
1. set rootContext.flags = 1
2. before `tickContext()`, reset rootContext.flags = 0
3. inside `tickContext()`, it will call `CounterComponent.ngOnint()`,
so the `2nd` markDirty() is called.
4. and the `2nd` scheduleTick is called, `nothingScheduled` is true,
but rootContext.clean is not `_CLEAN_PROMISE` yet, since the `1st` markDirty tick
is still running.
5. So nowhere will reset the `rootContext.flags`.
6. then in the future, any other `markDirty()` call will not trigger the tick, since
`nothingScheduled` is always false.
So `nothingScheduled` means no tick is scheduled, `rootContext.clean === _CLEAN_PROMISE`
means no tick is running.
So we should set the flags to `rootContext` only when `no tick is scheudled or running`.

This commit refactors validators-related logic that is common across most of the directives.
A couple notes on this refactoring:
* common logic was moved to the `AbstractControlDirective` class (including `validator` and
`asyncValidator` getters)
* sync/async validators are now composed in `AbstractControlDirective` class eagerly when validators
are set with `_setValidators` and `_setAsyncValidators` calls and the result is stored in directive
instance (thus getters return cached versions of validator fn). This is needed to make sure composed
validator function remains the same (retains its identity) for a given directive instance, so that
this function can be added and later removed from an instance of an AbstractControl-based class
(like `FormControl`). Preserving validator function is required to perform proper cleanup (in followup
PRs) of the AbstractControl-based classes when a directive is destroyed.

The compiler uses a `Reference` abstraction to refer to TS nodes
that it needs to refer to from other parts of the source. Such
references keep track of any identifiers that represent the referenced
node.
Prior to this commit, the compiler (and specifically `ReferenceEmitter`
classes) assumed that the reference identifiers are always free standing.
In other words a reference identifier would be an expression like
`FooDirective` in the expression `class FooDirective {}`.
But in UMD/CommonJS source, a reference can actually refer to an "exports"
declaration of the form `exports.FooDirective = ...`.
In such cases the `FooDirective` identifier is not free-standing
since it is part of a property access, so the `ReferenceEmitter`
should take this into account when emitting an expression that
refers to such a `Reference`.
This commit changes the `LocalIdentifierStrategy` reference emitter
so that if the `node` being referenced is not a declaration itself and
is in the current file, then it should be used directly, rather than
trying to use one of its identifiers.

This commit fixes a bug when `useAbsoluteUrl` is set to true and
`ServerPlatformLocation` infers the base url from the supplied
`url`. User should explicitly set the `baseUrl` when they turn on
`useAbsoluteUrl`.
Breaking change:
If you use `useAbsoluteUrl` to setup `platform-server`, you now need to
also specify `baseUrl`.
We are intentionally making this a breaking change in a minor release,
because if `useAbsoluteUrl` is set to `true` then the behavior of the
application could be unpredictable, resulting in issues that are hard to
discover but could be affecting production environments.

Use the bypass-specific Trusted Types policy for automatically upgrade
any values from custom sanitizers or the bypassSecurityTrust functions
to a Trusted Type. Update tests to reflect the new behavior.
PR Close#39218
When an application uses a custom sanitizer or one of the
bypassSecurityTrust functions, Angular has no way of knowing whether
they are implemented in a secure way. (It doesn't even know if they're
introduced by the application or by a shady third-party dependency.)
Thus using Angular's main Trusted Types policy to bless values coming
from these two sources would undermine the security that Trusted Types
brings.
Instead, introduce a Trusted Types policy called angular#unsafe-bypass
specifically for blessing values from these sources. This allows an
application to enforce Trusted Types even if their application uses a
custom sanitizer or the bypassSecurityTrust functions, knowing that
compromises to either of these two sources may lead to arbitrary script
execution. In the future Angular will provide a way to implement
custom sanitizers in a manner that makes better use of Trusted Types.

Sanitizers in Angular currently return strings, which will then
eventually make their way down to the DOM, e.g. as the value of an
attribute or property. This may cause a Trusted Types violation. As a
step towards fixing that, make it possible to return Trusted Types from
the SanitizerFn interface, which represents the internal sanitization
pipeline. DOM renderer interfaces are also updated to reflect the fact
that setAttribute and setAttributeNS must be able to accept Trusted
Types.

The JIT compiler uses the Function constructor to compile arbitrary
strings into executable code at runtime, which causes Trusted Types

Trusted Types compatible Function constructor introduced by Angular's
Trusted Types policy for JIT.
PR Close#39210
Introduce a Trusted Types policy for use by Angular's JIT compiler named
angular#unsafe-jit. As the compiler turns arbitrary untrusted strings
into executable code at runtime, using Angular's main Trusted Types
policy does not seem appropriate, unless it can be ensured that the
provided strings are indeed trusted. Until then, this JIT policy can be
allowed by applications that rely on the JIT compiler but want to
enforce Trusted Types, knowing that a compromise of the JIT compiler can
lead to arbitrary script execution. In particular, this is required for
enabling Trusted Types in Angular unit tests, since they make use of the
JIT compiler.
Also export the internal Trusted Types definitions from the core package
so that they can be used in the compiler package.

When an input name is part of the directive selector, it would be good to return the directive as well
when performing 'go to definition' or 'go to type definition'. As an example, this would allow
'go to type definition' for ngIf to take the user to the NgIf directive.
'Go to type definition' would otherwise return no results because the
input is a generic type. This would also be the case for all primitive
input types.

Angular treats constant values of attributes and properties in templates
as secure. This means that these values are not sanitized, and are
instead passed directly to the corresponding setAttribute or setProperty
function. In cases where the given attribute or property is
security-sensitive, this causes a Trusted Types violation.
To address this, functions for promoting constant strings to each of the
three Trusted Types are introduced to Angular's private codegen API. The
compiler is updated to wrap constant strings with calls to these
functions as appropriate when constructing the `consts` array. This is
only done for security-sensitive attributes and properties, as
classified by Angular's dom_security_schema.

Previously, inline exports of the form `exports.foo = <implementation>;` were
being interpreted (by the ngtsc `PartialInterpeter`) as `Reference` objects.
This is not what is desired since it prevents the value of the export
from being unpacked, such as when analyzing `NgModule` declarations:
```
exports.directives = [Directive1, Directive2];
@NgImport({declarations: [exports.directives]})
class AppModule {}
```
In this example the interpreter would think that `exports.directives`
was a reference rather than an array that needs to be unpacked.

When ngcc is configured to run with the `--use-program-dependencies`
flag, as is the case in the CLI's asynchronous processing, it will scan
all source files in the program, starting from the program's root files
as configured in the tsconfig. Each individual root file could
potentially rescan files that had already been scanned for an earlier
root file, causing a severe performance penalty if the number of root
files is large. This would be the case if glob patterns are used in the
"include" specification of a tsconfig file.
This commit avoids the performance penalty by keeping track of the files
that have been scanned across all root files, such that no source file
is scanned multiple times.

Function", use the Trusted Types compatible function constructor exposed

PR Close#39209
Chrome currently does not support passing TrustedScript to the Function
constructor, and instead fails with a Trusted Types violation when
called. As the Function constructor is used in a handful of places
within Angular, such as in the JIT compiler and named_array_type, the
workaround proposed on the following page is implemented:
https://github.com/w3c/webappsec-trusted-types/wiki/Trusted-Types-for-function-constructor
To be precise, it constructs a string representing an anonymous function
in a way that is equivalent to what the Function constructor does,
promotes it to a TrustedScript and then calls eval.
To facilitate backwards compatibility, new Function is used directly in
environments that do not support Trusted Types.

return Foo;
})();
exports.Foo = Foo_1 = __decorate(SomeDecorator, Foo);

Such inline classes were ignored and not processed by ngcc.

`PropertyAccessExpression` nodes for `InlineDeclaration` types.
PR Close#38959
Previously the `ConcreteDeclaration` and `InlineDeclaration` had
different properties for the underlying node type. And the `InlineDeclaration`
did not store a value that represented its declaration.
It turns out that a natural declaration node for an inline type is the
expression. For example in UMD/CommonJS this would be the `exports.<name>`
property access node.
So this expression is now used for the `node` of `InlineDeclaration` types
and the `expression` property is dropped.
To support this the codebase has been refactored to use a new `DeclarationNode`
type which is a union of `ts.Declaration|ts.Expression` instead of `ts.Declaration`
throughout.

Previously `getDeclaration()` would only return the first node that matched
the name passed in and then assert the predicate on this single node.
It also only considered a subset of possible declaration types that we might
care about.
Now the function will parse the whole tree collecting an array of all the
nodes that match the name. It then filters this array based on the predicate
and only errors if the filtered array is empty.
This makes this function much more resilient to more esoteric code formats
such as UMD.
