Prior to this commit, listeners order was not preserved in case we coalesce them to avoid triggering unnecessary change detection cycles. For performance reasons we were attaching listeners to existing events at head (always using first listener as an anchor), to avoid going through the list, thus breaking the order in which listeners are registered. In some scenarios this order might be important (for example with `ngModelChange` and `input` listeners), so this commit updates the logic to put new listeners at the end of the list. In order to avoid performance implications, we keep a pointer to the last listener in the list, so adding a new listener takes constant amount of time.

We need to be clearer to developers who upgrade to v9 (next) and get this
error, why they have a problem and what they have to do about it.
Once we have a better CLI schematics story, where this import will be
included by default in new applications and a CLI migration will add it
when upgrading apps to v9, we could simplify or remove this error message.

Fixes an issue where Ivy incorrectly inserts items in the beginning of an `ngFor`, if the `ngFor` is set on an `ng-container`. The issue comes from the fact that we choose the `ng-container` comment node as the anchor point before which to insert the content, however the node might be after any of the nodes inside the container. These changes switch to picking out the first node inside of the container instead.

Historically bind() used to be a separate instruction. With a series of
refactoring it became a utility function but after recent code changes
it does not provide any valuable abstraction / help. On the contrary -
it can be seen as a performance problem (forces unnecessary comparison to
`NO_CHANGE` during change detection).

Prior to this commit, complex expressions (that require additional statements to be generated) were handled incorrectly in case they were used in attributes annotated with i18n flags. The problem was caused by the fact that extra statements were not appended to the temporary vars block, so they were missing in generated code. This commit updated the logic to use the `convertPropertyBinding`, which contains the necessary code to append extra statements. The `convertExpressionBinding` function was removed as it duplicates the `convertPropertyBinding` one (for the most part) and is no longer used.

Prior to this fix if a `NO_CHANGE` value was assigned to a binding, or
an interpolation value rendererd a `NO_CHANGE` value, then the presence
of that value would cause the internal counter index values to not
increment properly. This patch ensures that this doesn't happen and
that the counter/bitmask values update accordingly.

PR #32154 introduced `platform` and `any` for `providedIn` and the doc has a minor typo.

Since property binding metadata storage is guarded with the ngDevMode now
and several instructions were merged together, we can simplify the way we
store and read property binding metadata.

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).

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.

BREAKING CHANGE: Injector.get now accepts abstract classes to return

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.

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).
