With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.
**Before**
```ts
import {XhrFactory} from '@angular/common/http';
```
**After**
```ts
import {XhrFactory} from '@angular/common';
```

A previous commit implemented a streamlined performance metric reporting
system for the compiler-cli, controlled via the compiler option
`tracePerformance`.
This commit adds a custom Bazel flag rule //packages/compiler-cli:ng_perf
to the repository, and wires it through to the `ng_module` implementation
such that if the flag is set, `ng_module` will produce perf results as part
of the build. The underlying mechanism of `//:ng_perf` is not exported from
`@angular/bazel` as a public rule that consumers can use, so there is little
risk of accidental dependency on the contents of these perf traces.
An alias is added so that `--ng_perf` is a Bazel flag which works in our
repository.

ngtsc has an internal performance tracing package, which previously has not
really seen much use. It used to track performance statistics on a very
granular basis (microseconds per actual class analysis, for example). This
had two problems:
* it produced voluminous amounts of data, complicating the analysis of such
results and providing dubious value.
* it added nontrivial overhead to compilation when used (which also affected
the very performance of the operations being measured).
This commit replaces the old system with a streamlined performance tracing
setup which is lightweight and designed to be always-on. The new system
tracks 3 metrics:
* time taken by various phases and operations within the compiler
* events (counters) which measure the shape and size of the compilation
* memory usage measured at various points of the compilation process
If the compiler option `tracePerformance` is set, the compiler will
serialize these metrics to a JSON file at that location after compilation is
complete.

Some `elements` tests rely on `window.customElements` being available.
On browsers where this was not present, the tests were skipped.
This commit includes the `@webcomponents/custom-elements` polyfill in
order to be able to run all `elements` tests on older browsers, which do
not natively support Custom Elements.
This, also, fixes the [saucelabs_ivy][1] and [saucelabs_view_engine][2]
CI jobs (part of the `monitoring` workflow), which have been failing
recently on IE 11 (probably due to the update to TS 4.2.3).

TypeScript 4.2 has changed its emitted syntax for synthetic constructors
when using `downlevelIteration`, which affects ES5 bundles that have
been downleveled from ES2015 bundles. This is typically the case for UMD
bundles in the APF spec, as they are generated by downleveling the
ESM2015 bundle into ES5. The reflection capabilities in the runtime need
to recognize this new form to correctly deal with synthesized
constructors, as otherwise JIT compilation could generate invalid
factory functions.

The Ivy Language Service uses the compiler's template type-checking engine,
which honors the configuration in the user's tsconfig.json. We recommend
that users upgrade to `strictTemplates` mode in their projects to take
advantage of the best possible type inference, and thus to have the best
experience in Language Service.
If a project is not using `strictTemplates`, then the compiler will not
leverage certain type inference options it has. One case where this is very
noticeable is the inference of let- variables for structural directives that
provide a template context guard (such as NgFor). Without `strictTemplates`,
these guards will not be applied and such variables will be inferred as
'any', degrading the user experience within Language Service.
This is working as designed, since the Language Service _should_ reflect
types exactly as the compiler sees them. However, the View Engine Language
Service used its own type system that _would_ infer these types even when
the compiler did not. As a result, it's confusing to some users why the
Ivy Language Service has "worse" type inference.
To address this confusion, this commit implements a suggestion diagnostic
which is shown in the Language Service for variables which could have been
narrowed via a context guard, but the type checking configuration didn't
allow it. This should make the reason why variables receive the 'any' type
as well as the action needed to improve the typings much more obvious,
improving the Language Service experience.

When a contributor was removed from `contributors.json`, the
corresponding image should also be removed from
`aio/content/images/bios/`. However, this was often overlooked,
resulting in unused images remaining in `aio/content/images/bios/`.
This commit adds a check to ensure that all images in
`aio/content/images/bios/` are referenced in `contributors.json`.
PR Close#41290
This commit removes some contributor images that are no longer
referenced in `contributors.json` (i.e. they belong to contributors that

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.

The `ɵɵInjectorDef` interface is internal and should not be published publicly

type, `ɵɵInjectorDeclaration`, for this instead, which appears in the typings

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

the compiler.

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).
