Previously, there could be identical template/listener function names
for a component's template, if it had multiple similarly structured
nested sub-templates or listeners.
This resulted in build errors:
`Identifier '<SOME_IDENTIFIER>' has already been declared`
This commit fixes this by ensuring that the template index is included
in the `contextName` passed to the `TemplateDefinitionBuilder`
responsible for processing nested sub-templates.
Similarly, the template or element index is included in the listener
names.

This PR assures that content projection works if an <ng-content> tag is
placed inside an <ng-template> in one component and that <ng-template>
is inserted into a different component. It fixes a bug where the
projection instruction code would walk up the insertion tree to find
selector data instead of the declaration tree.

Prior to this change, ICU extraction logic was not taking into account nested bindings (that look like this: �0:1�) and only accounted for top level bindings (like this �0�). As a result, ICUs were not parsed and remained as text in the output. Now the extraction logic (regular expressions) take into account the nested bindings format as well.

In some cases in our tests we can define multiple overrides for a given class. As a result, only the last override is actually applied due to the fact that we store overrides in a Type<->Override map.

This behavior is more inline with the previous TestBed.

Normally functions that return `ModuleWithProvider` objects should parameterize
the return type to include the type of `NgModule` that is being returned. For
example `forRoot(): ModuleWithProviders<RouterModule>`.
But in some cases, especially those generated by nccc, these functions to not
explicitly declare `ModuleWithProviders` as their return type. Instead they
return a "intersection" type, one of whose members is a type literal that
declares the `NgModule` type returned. For example:
`forRoot(): CustomType&{ngModule:RouterModule}`.
This commit changes the `NgModuleDecoratorHandler` so that it can extract
the `NgModule` type from either kind of declaration.
PR Close#27326
Exported functions or static method that return a `ModuleWithProviders`
compatible structure need to provide information about the referenced
`NgModule` type in their return type.
This allows ngtsc to be able to understand the type of `NgModule` that is
being returned from calls to the function, without having to dig into the
internals of the compiled library.
There are two ways to provide this information:
* Add a type parameter to the `ModuleWithProviders` return type. E.g.
```
static forRoot(): ModuleWithProviders<SomeNgModule>;
```
* Convert the return type to a union that includes a literal type. E.g.
```
static forRoot(): (SomeOtherType)&{ngModule:SomeNgModule};
```
This commit updates the rendering of typings files to include this type
information on all matching functions/methods.

Prior to this commit, we had two different modes for change detection
execution for Ivy, depending on whether you called `bootstrap()` or
`renderComponent()`. In the former case, we would complete creation
mode for all components in the tree before beginning update mode for
any component. In the latter case, we would run creation mode and
update mode together for each component individually.
Maintaining code to support these two different execution orders was
unnecessarily complex, so this commit aligns the two bootstrapping
mechanisms to execute in the same order. Now creation mode always
runs for all components before update mode begins.
This change also simplifies our rendering logic so that we use
`LView` flags as the source of truth for rendering mode instead of
`rf` function arguments. This fixed some related bugs (e.g. calling
`ViewRef.detectChanges` synchronously after the view's creation
would create view nodes twice, view queries would execute twice, etc).

This option means guards and resolvers will ignore changes when a provided predicate function returns `false`. This supports use cases where an application needs to ignore some param updates but not others. For example, changing a sort param in the URL might need to be ignored, whereas changing the a `project` param might require re-run of guards and resolvers.

Currently whenever the upgrade test helper fails to load a given AngularJS version, the error that will be rejected is technically not an error because the `onerror` callback is not returning an error, but an "ErrorEvent".
Since that `ErrorEvent` is basically just rejected, browsers will print
the error as followed:
```
Failed: [object Event]
```
This is not helpful at all and also implies that there _might_ be more
information hidden within the `Event` instance. Unfortunately that's not
the case (at least on browsers we test against) and the logic to extract
the data from the event would be not worth the effort, we just return a
simple custom `Error` that won't imply that there is more information
hidden.

In ngUpgrade (dynamic) we create a dynamic Angular `Directive` that wraps AngularJS components
that are being upgraded. The constructor of this `Directive` class returns a different instance
than `this`. It is this instance that actually contains the life-cycle hook handlers.
This would break in ivy, since the methods on the prototype of the original class are wired up,
rather than the instance methods. This results in hooks like `ngOnInit` not being called.
This commit refactors the code to extend the inner class that was being returned so that the
prototype chain is correct for both ViewEngine and ivy.
This change resolves a number of failing ivy tests, but also exposes other failures that were
masked by this issue. The tests have been updated accordingly.

`NgModule` requires that `Component`s/`Directive`s/`Pipe`s are listed in
declarations, and that each `Component`s/`Directive`s/`Pipe` is declared
in exactly one `NgModule`. This change adds runtime checks to ensure
that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the
codebase to verify that same set of semantics hold. Due to current
design there does not seem to be an easy way to share the two checks
because JIT deal with references where as AoT deals with AST nodes.

ngcc would feed ngtsc with the function declaration inside of an IIFE as

TypeScript's `ts.Symbol.valueDeclaration`. ngtsc however only considered
variable decls and actual class decls as potential class declarations,
so given the function declaration node it would fail to generate the
`setClassMetadata` call.

Prior to this change, we were unable to match directives using `ng-template` tags (for example the following selector would not work even though there might be some <ng-template>s in a template: `ng-template[directiveA]`. As a result, that broke some components that relies on such selectors to work. In order to resolve the problem, we now pass tag name to the `template` instruction (where we passed `null` before) and this tag name is used for matching at runtime. This update should also help support projecting containers, because the tag name is required to properly match such elements.

place, such that TypeScript print logic will only generate JS code.

In Ivy, a pure call to `setClassMetadata` is inserted to retain the
information that would otherwise be lost while eliding the Angular
decorators. In the past, the Angular constructor decorators were
wrapped inside of an anonymous function which was only evaluated once
`ReflectionCapabilities` was requested for such metadata. This approach
prevents forward references from inside the constructor parameter
decorators from being evaluated before they are available.
In the `setClassMetadata` call, the constructor parameters were not wrapped
within an anonymous function, such that forward references were evaluated
too early, causing runtime errors.
This commit changes the `setClassMetadata` call to pass the constructor
parameter decorators inside of an anonymous function again, such that
forward references are not resolved until requested by
`ReflectionCapabilities`, therefore avoiding the early reads of forward refs.

In order to keep the bazel bin directory as clean as possible, we should not write definition files that are not relevant to a `ng_package` to an undesired location in the bazel bin directory. This currently just happens because we only filter out external definition files while we also should filter out definitions that aren't just in the current package.
The `packager.ts` file currently tries to write these files to the package, but fails because those are not inside of the current package. So the logic to create a relative path for the file fails, and the definition will be copied to a location like:
