Prior to this change, the logic that compiles Injectable in JIT mode used incorrect configuration that triggers a problem when `ChangeDetectorRef` is used as a dependency. This commit updates the logic to generate correct inject instruction to add the `ChangeDetectorRef` dependency in case it's requested in @Injectable class.

Source-maps in the wild could be badly formatted,
causing the source-map flattening processing to fail
unexpectedly. Rather than causing the whole of ngcc
to crash, we gracefully fallback to just returning the
generated source-map instead.
PR Close#35718
Previously when rendering flattened source-maps, it was assumed that no
mapping would come from a line that is outside the lines of the actual
source content. It turns out this is not a valid assumption.
Now the code that renders flattened source-maps will handle such
mappings, with the additional benefit that the rendered source-map
will only contain mapping lines up to the last mapping, rather than a
mapping line for every content line.
Fixes#35709

If a package has a source-map but it does not provide
the actual content of the sources, then the source-map
flattening was crashing.
Now we ignore such mappings that have no source
since we are not able to compute the merged
mapping if there is no source file.

In #35702, the payload size limit for Ivy builds was bumped to account
for small incremental increases in recent PRs. The ViewEngine size has
also increased similarly (~500B), but it was not updated in #35702,
because its total increase was just below the 500B error threshold (by
6B).
This commit bumps the ViewEngine size limit too.
Note: Any investigation for the Ivy size increase (as a follow-up
to #35702) will most likely also apply to ViewEngine, since the size was
increased by the same amount.

This commit updates AIO payload size limit that is triggering a problem after merging 0bc35a71e2.

If an injectable has a `useClass`, Ivy injects the token in `useClass`, rather than the original injectable, if the injectable is re-provided under a different token. The correct behavior is that it should inject the re-provided token, no matter whether it has `useClass`.

It's possible to pass a directive as an input to itself. Consider:
```html
<some-cmp #ref [value]="ref">
```
Since the template type-checker attempts to infer a type for `<some-cmp>`
using the values of its inputs, this creates a circular reference where the
type of the `value` input is used in its own inference:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: _t0});
```
Obviously, this doesn't work. To resolve this, the template type-checker
used to generate a `null!` expression when a reference would otherwise be
circular:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: null!});
```
This effectively asks TypeScript to infer a value for this context, and
works well to resolve this simple cycle. However, if the template
instead tries to use the circular value in a larger expression:
```html
<some-cmp #ref [value]="ref.prop">
```
The checker would generate:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: (null!).prop});
```
In this case, TypeScript can't figure out any way `null!` could have a
`prop` key, and so it infers `never` as the type. `(never).prop` is thus a
type error.
This commit implements a better fallback pattern for circular references to
directive types like this. Instead of generating a `null!` in place for the
reference, a type is inferred by calling the type constructor again with
`null!` as its input. This infers the widest possible type for the directive
which is then used to break the cycle:
```typescript
var _t0 = SomeCmp.ngTypeCtor(null!);
var _t1 = SomeCmp.ngTypeCtor({value: _t0.prop});
```
This has the desired effect of validating that `.prop` is legal for the
directive type (the type of `#ref`) while also avoiding a cycle.

NG6002/NG6003 are errors produced when an NgModule being compiled has an
imported or exported type which does not have the proper metadata (that is,
it doesn't appear to be an @NgModule, or @Directive, etc. depending on
context).
Previously this error message was a bit sparse. However, Github issues show
that this is the most common error users receive when for whatever reason
ngcc wasn't able to handle one of their libraries, or they just didn't run
it. So this commit changes the error message to offer a bit more useful
context, instructing users differently depending on whether the class in
question is from their own project, from NPM, or from a monorepo-style local
dependency.

When binding to `[style]` we correctly sanitized/unwrapped properties but we did not do it for the object itself.
```
@HostBinding("style")
style: SafeStyle = this.sanitizer.bypassSecurityTrustStyle(
"background: red; color: white; display: block;"
);
```
Above code would fail since the `[style]` would not unwrap the `SafeValue` and would treat it as object resulting in incorrect behavior.

To avoid breaking the app, we use a no-op `Storage` implementation if
`window.localStorage` is not available.

On API docs pages for Angular packages (e.g. https://angular.io/api/common), we show all primary and secondary entry-points. Following a link to one of the secondary entry-points (e.g. https://angular.io/api/common/http), navigates the docs page for the secondary entry-point, where it is incorrectly (and misleadingly) labelled as PACKAGE and not as an entry-point.
Implemented a new ENTRY-POINT label and add support for correctly differentiating between entry-points and packages.

The library used by ngcc to update the source files (MagicString) is able
to generate a source-map but it is not able to account for any previous
source-map that the input text is already associated with.
There have been various attempts to fix this but none have been very
successful, since it is not a trivial problem to solve.
This commit contains a novel approach that is able to load up a tree of
source-files connected by source-maps and flatten them down into a single
source-map that maps directly from the final generated file to the original
sources referenced by the intermediate source-maps.

Currently we resolve the `NgModuleRef.componentFactoryResolver` by going through the injector, but the problem is that `ComponentFactoryResolver` has a dependency on `NgModuleRef`, which means that if the module that's attached to the ref tries to inject `ComponentFactoryResolver` in its constructor, we'll create a circular dependency which throws at runtime.
These changes resolve the issue by creating the `ComponentFactoryResolver` manually ahead of time without going through the injector. We can do this safely, because the only dependency for the resolver is the current module ref which is providing it.
Aside from fixing the issue, another advantage to this approach is that it should reduce the amount of generated JS, because it removes a getter and a provider definitio.
Fixes#35580.

Technically, function definitions can live anywhere because they are
hoisted. However, in this case Closure optimizations break when exported
function definitions are referred in another static object that is
exported.
The bad pattern is:
```
exports const obj = {f};
export function f() {...}
```
which turns to the following in Closure's module system:
```
goog.module('m');
exports.obj = {f};
function f() {...}
exports.f = f;
```
which badly optimizes to (note module objects are collapsed)
```
var b = a; var a = function() {...}; // now b is undefined.
```
This is an optimizer bug and should be fixed in Closure, but in the
meantime this change is a noop and will unblock other changes we want to
make.

Currently if TestBed detects that TestBed.overrideModule was used for module X, transitive scopes are recalculated recursively for all modules that X imports and previously calculated data (stored in cache) is ignored. This behavior was introduced in https://github.com/angular/angular/pull/33787 to fix stale transitive scopes issue (cache was not updated if module overrides are present).
The perf issue comes from a "diamond" problem, where module X is overridden which imports modules A and B, which both import module C. Under previous logic, module C gets its transitive deps recomputed multiple times, during the recompute for both A and B. For deep graphs and big common/shared modules this can be super costly.
This commit updates the logic to recalculate ransitive scopes for the overridden module, while keeping previously calculated scopes of other modules untouched.

User needs to use `elem.addEventListener('scroll', listener, {passive: true});`
or implements their own EventManagerPlugin to do that.

this commit introduces a temp solution to allow user to define the passive event names
in zone.js configurations.
User can define a global varibale like this.
```
(window as any)['__zone_symbol__PASSIVE_EVENTS'] = ['scroll'];
```
to let all `scroll` event listeners passive.
