Currently, when importing `BrowserAnimationsModule`, Angular uses `AnimationRenderer`
as the renderer. When the root view is removed, the `AnimationRenderer` defers the actual
work to the `TransitionAnimationEngine` to do this, and the `TransitionAnimationEngine`
doesn't actually remove the DOM node, but just calls `markElementAsRemoved()`.
The actual DOM node is not removed until `TransitionAnimationEngine` "flushes".
Unfortunately, though, that "flush" will never happen, since the root view is being
destroyed and there will be no more flushes.
This commit adds `flush()` call when the root view is being destroyed.
BREAKING CHANGE:
DOM elements are now correctly removed when the root view is removed.
If you are using SSR and use the app's HTML for rendering, you will need
to ensure that you save the HTML to a variable before destorying the
app.
It is also possible that tests could be accidentally relying on the old behavior by
trying to find an element that was not removed in a previous test. If
this is the case, the failing tests should be updated to ensure they
have proper setup code which initializes elements they rely on.

ActivatedRoute.fragment was typed as Observable<string> but could emit
both null and undefined due to incorrect non-null assertion. These
non-null assertions have been removed and fragment has been retyped to
string | null.
BREAKING CHANGE:
Strict null checks will report on fragment potentially being null.
Migration path: add null check.

The `ɵɵInjectorDef` interface is internal and should not be published publicly
as part of libraries. This commit updates the compiler to render an opaque
type, `ɵɵInjectorDeclaration`, for this instead, which appears in the typings
for compiled libraries.
PR Close#41119
Th `ɵɵFactoryDef` type will appear in published libraries, via their typings
files, to describe what type dependencies a DI factory has. The parameters
on this type are used by tooling such as the Language Service to understand
the DI dependencies of the class being created by the factory.
This commit moves the type to the `public_definitions.ts` file alongside
the other types that have a similar role, and it renames it to `ɵɵFactoryDeclaration`
to align it with the other declaration types such as `ɵɵDirectiveDeclaration`
and so on.
PR Close#41119
These types are only used in the generated typings files to provide
information to the Angular compiler in order that it can compile code
in downstream libraries and applications.
This commit aliases these types to `unknown` to avoid exposing the
previous alias types such as `ɵɵDirectiveDef`, which are internal to
the compiler.

In #41253 the size of contributor images was limited, but
some images were already too large. So an exclusion list
was added. These images have now been reduced, so
the exclusion list is no longer needed.
The files were reduced by a combination of running them through the
https://tinyjpg.com/ online service and manually setting their size to
168px wide or tall using the MacOS Image Preview app.

Previously presence of both [class] and [className] bindings on an element was treated as compiler error (implemented in 6f203c9575). Later, the situation was improved to actually allow both bindings to co-exist (see a153b61098), however the compiler check was not removed completely. The only situation where the error is thrown at this moment is when static (but with interpolation) and bound `class` attributes are present on an element, for ex.:
```
<div class="{{ one }}" [class]="'two'"></div>
```
In the current situation the error is acually misleading (as it refers to `[className]`).
This commit removes the mentioned compiler check as obsolete and makes the `class` and `style` attribute processing logically the same (the last occurrence is used to compute the value).

This commit fixes the behavior when creating a type constructor for a directive when the following
conditions are met.
1. The directive has bound generic parameters.
2. Inlining is not available. (This happens for language service compiles).
Previously, we would throw an error saying 'Inlining is not supported in this environment.' The
compiler would stop type checking, and the developer could lose out on getting errors after the
compiler gives up.
This commit adds a useInlineTypeConstructors to the type check config. When set to false, we use
`any` type for bound generic parameters to avoid crashing. When set to true, we inline the type
constructor when inlining is required.

The partial declaration of a component includes the list of directives
that are used in its template, including some metadata of the directive
which can be used during actual compilation of the component. Used
components are currently part of this list, as components are also
directives. This commit splits the used components into a dedicate
property in the partial declaration, which allows for template
compilation to optimize the generated code for components.

This commit complements the support for the `__spreadArray` helper that
was added in microsoft/TypeScript#41523. The prior helpers `__spread`
and `__spreadArrays` used the `__read` helper internally, but the helper
is now emitted as an argument to `__spreadArray` so ngcc now needs to
support evaluating it statically. The real implementation of `__read`
reads an iterable into an array, but for ngcc's static evaluation
support it is sufficient to only deal with arrays as is. Additionally,
the optional `n` parameter is not supported as that is only emitted for
array destructuring syntax, which ngcc does not have to support.
PR Close#41201
In TypeScript 4.2 the `__spread` and `__spreadArrays` helpers were both
replaced by the new helper function `__spreadArray` in
microsoft/TypeScript#41523. These helpers may be used in downleveled
JavaScript bundles that ngcc has to process, so ngcc has the ability to
statically detect these helpers and provide evaluation logic for them.
Because Angular is adopting support for TypeScript 4.2 it becomes
possible for libraries to be compiled by TypeScript 4.2 and thus ngcc
has to add support for the `__spreadArray` helper. The deprecated
`__spread` and `__spreadArrays` helpers are not affected by this change.

The recently introduced typings-only mode in ngcc would incorrectly
write compiled JavaScript files if typings-only mode was requested, in
case the typings of the entry-point had already been processed in a
prior run of ngcc. The corresponding format property for which the
JavaScript files were written were not marked as processed, though, as
the typings-only mode excluded the format property itself from being
marked as processed. Consequently, subsequent runs of ngcc would not
consider the entry-point to have been processed and recompile the
JavaScript bundle once more, resulting in duplicate ngcc imports.
