This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.
BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.
```ts
import '@angular/localize';
```
For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.

DebugElement.query also searches elements that may have been created
outside of Angular (ex: with `document.appendChild`). The current
behavior attempts to get the LContext of these nodes but throws an error
because the LContext does not exist.

Commit 904a2018e0 introduced a new migration for
undecorated classes with decorated Angular class members. Currently the migration
always calls `tree.beginUpdate` and `tree.commitUpdate` (even if there are no changes).
This causes unnecessary updates to be reported to developers running `ng update`. Once
an update is commited, the CLI will report the update regardless of whether any changes were
made or not.
This behavior can be observed in the `ng_update_migrations` integration test. See:
https://circleci.com/gh/angular/angular/438470#tests/containers/3. Notice how all
source files are denoted as `UPDATED` (even though there are no changes).

This patch introduces a new micro benchmark that performance tests
against map-based style and class bindings in Ivy running together
on the same element.

Extend the vocabulary of the `providedIn` to also include `'platform'` and `'any'`` scope.
```
@Injectable({
providedId: 'platform', // tree shakable injector for platform injector
})
class MyService {...}

Initially the `missing-injectable` migration was only being used
in google3. Wiring the migration up in the CLI migrations was
planned to be done in a follow-up.

TestBed.get is not type safe, fixing it would be a massive breaking
change. The Angular team has proposed replacing it with TestBed.inject
and deprecate TestBed.get.
Deprecation from TestBed.get will come as a separate commit.
Issue #26491Fixes#29905
BREAKING CHANGE: Injector.get now accepts abstract classes to return
type-safe values. Previous implementation returned `any` through the
deprecated implementation.

Currently the undecorated classes migration decorates base classes if no
explicit constructor is defined on all classes in the inheritance chain.
We only want to decorate base classes which define a constructor that is
inherited. Additionally for best practice, all classes in between the class
that inherits the constructor and the one that defines it are also decorated.

The `undecorated-classes-with-di` migration currently creates invalid object literals from parsed
NGC metadata files if there are object literal properties with keys that contain special characters.
e.g. consider a decorated base class with a host binding using `[class.X]`. Currently the migration
parses and converts the metadata to TypeScript code but incorrectly uses `[class.X]` unquoted as
identifier.

Apparently the names of the bazel test targets in the schematics are

ec4381dd40 enabled Ivy by default. This is
problematic as migrations like `undecorated-classes-with-di` depend on the
`AngularCompilerProgram` (NGC) in order to perform the migration from
version 8 to version 9. In order to ensure that the migration always runs
with NGC (and doesn't get the `NgtscProgram`), we need to explicitly disable
ivy when creating the `@angular/compiler-cli` program for the migration.

Reworks the compiler to output the factories for directives, components and pipes under a new static field called `ngFactoryFn`, instead of the usual `factory` property in their respective defs. This should eventually allow us to inject any kind of decorated class (e.g. a pipe).
**Note:** these changes are the first part of the refactor and they don't include injectables. I decided to leave injectables for a follow-up PR, because there's some more cases we need to handle when it comes to their factories. Furthermore, directives, components and pipes make up most of the compiler output tests that need to be refactored and it'll make follow-up PRs easier to review if the tests are cleaned up now.
This is part of the larger refactor for FW-1468.

Binding metadata are only needed:
- for property bindings;
- when TestBed tests are being run.
This commit guards binding metadata storage with the ngDevMode flag
which saves ~6% of a proerty binding processing time in the production
mode (and reduces bundle size).

After a series of recent refactorings `enterView` and `leaveView` became
identical. This PR merges both into one concept of view selectio (similar
to a node selection). This reduces number of concepts and code size.

This commit removes all the (duplicated) logic of setting lView[BINDING_INDEX]
from `enterView`. `enterView` is on the critcal path perf-wise so we should
avoid having any logic in there and minimise memory read / write.
This simple refactoring in this PR reduces time spent in noop change detection
by ~12% (from ~800ms down to ~700ms on a local machine where measurements were
taken).
PR Close#32263
Prior to this change, the `BINDING_INDEX` of a given lView was reset after processing a template. However change detection can be triggered as a result of View queries processing, thus leading to subsequent `refreshView` call (and executing a template), which in turn operates with the binding index that is not reset after the previous `refreshView` call. This commit updates the logic to reset binding index before we execute a template, so binding index is correct for instructions inside template function.

This commit drops our custom, change-detection specific, equality comparison util
in favour of the standard Object.is which has desired semantics.
There are multiple advantages of this approach:
- less code to maintain on our end;
- avoid NaN checks if both values are equal;
- re-write NaN checks so we don't trigger V8 deoptimizations.
