Previously the style encapsulation attributes(_nghost-* and _ngcontent-*) created on the server could overlap with the attributes and styles created by the client side app when it botstraps. In case the client is bootstrapping a lazy route, the client side styles are added before the server-side styles are removed. If the components on the client are bootstrapped in a different order than on the server, the styles generated by the client will cause the elements on the server to have the wrong styles.
The fix puts the styles and attributes generated on the server in a completely differemt space so that they are not affected by the client generated styles. The client generated styles will only affect elements bootstrapped on the client.

After #24113 there is 2 `TNode` in those tests:
- 1 for the host,
- 1 for the text node.
The PR #23924 status was green because it branched off master before #24113 was
merged in.

Closure Compiler in some configurations complains about duplicate
imports. This change replaces the export-with-import with an export of
the imported symbol.

This PR tackles a simple case where ViewRef definition point (<ng-template>) is the
same as the insertion point (ViewContainerRef requested on the said <ng-template>).
For this particular case we can assume that we know a container into which a given
view will be inserted when a view is created. This is not true fall all the possible
cases so follow-up PR will be needed to extend this basic implementation.

This commit builds out enough of the JIT compiler to render
//packages/core/test/bundling/todo, and allows the tests to run in
JIT mode.
To play with the app, run:
bazel run --define=compile=jit //packages/core/test/bundling/todo:prodserver

Fixes#23280, #23133.
This fix lets code access DOM types like Node, HTMLElement in the code. These are invariant across requests and the corresponding classes from Domino can be safely provided during platform initialization.
This is needed for the current sanitizer to work properly on platform-server. Also allows HTML types in injection - Ex. `@inject(DOCUMENT) doc: Document`.

Previously event handlers on the server were setup directly. This change makes it so that the event registration on the server go through EventManagerPlugin just like on client. This allows us to add custom event registration handlers on the server which allows us to hook up preboot event handlers cleanly.

In ngIvy directives matching (determining which directives are active based
on a CSS seletor) happens at runtime. This means that runtime needs to have
enough context to match directives. This PR takes care of cases where a directive's
selector should match bindings (ex. [foo]="exp") and event handlers (ex. (out)="do()").
In the mentioned cases we need to have binding / output "attributes" for directive's
CSS selector matching purposes. At the same time those are not regular attributes and
as such should not be reflected in the DOM.

Allows to write:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { pure: false } })
.createComponent(MenuComponent);
when you only want to set the `pure` metadata,
instead of currently:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { name: 'displayName', pure: false } })
.createComponent(MenuComponent);
which forces you to redefine the name of the pipe even if it is useless.

Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.
Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.
Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:
* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
Angular related transforms, which approximates the behavior of plain
tsc. This allows the main packages such as common to be tested with
the JIT compiler.
Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.

Short-circuitable expressions (using ternary & binary operators) could not use
the regular binding mechanism as it relies on the bindings being checked every
single time - the index is incremented as part of checking the bindings.
Then for pure function kind of bindings we use a different mechanism with a
fixed index. As such short circuiting a binding check does not mess with the
expected binding index.
Note that all pure function bindings are handled the same wether or not they
actually are short-circuitable. This allows to keep the compiler and compiled
code simple - and there is no runtime perf cost anyway.

This commit adds a mechanism by which the @angular/core annotations
for @Component, @Injectable, and @NgModule become decorators which,
when executed at runtime, trigger just-in-time compilation of their
associated types. The activation of these decorators is configured
by the ivy_switch mechanism, ensuring that the Ivy JIT engine does
not get included in Angular bundles unless specifically requested.

Since `versionedFiles` behaves in the exact same way as `files`, there
is no reaason to have both. Users should use `files` instead.
This commit deprecates the property and prints a warning when coming
across an asset-group that uses it. It should be completely removed in
a future version.
Note, it has also been removed from the default `ngsw-config.json`
template in angular/devkit#754.

Closure compiler with type based optimizations has a bug where externs for inherited static fields are not being honored. For Angular Elements this meant that 'observedAttributes' static field which is marked as an extern for the base HTMLElement class was getting renamed.
This commit works around the bug by using quoted access of 'observedAttributes' that explicitly prevents the renaming.
