Used to resolve resource URLs on `@Component` when used with JIT compilation.
```
@Component({
selector: 'my-comp',
templateUrl: 'my-comp.html', // This requires asynchronous resolution
})
class MyComponnent{
}
// Calling `renderComponent` will fail because `MyComponent`'s `@Compenent.templateUrl`
// needs to be resolved because `renderComponent` is synchronous process.
// renderComponent(MyComponent);
// Calling `resolveComponentResources` will resolve `@Compenent.templateUrl` into
// `@Compenent.template`, which would allow `renderComponent` to proceed in synchronous manner.
// Use browser's `fetch` function as the default resource resolution strategy.
resolveComponentResources(fetch).then(() => {
// After resolution all URLs have been converted into strings.
renderComponent(MyComponent);
});

Previously the todo app imported reflect-metadata, since it is a dependency
of JIT and the todo app tests run in both JIT and AOT modes. However, the
code doesn't get tree-shaken away in AOT mode.
This change adds a target //packages/core/test/bundling/util:reflect_metadata
which, depending on whether the compile flag is in JIT or AOT mode, either
includes reflect-metadata or is a no-op.
Not including reflect-metadata gets the compressed todo bundle down to 12.5 kB.

ngtsc is sufficiently capable now that it can compile hello_world
and todo and achieve equivalent results to ngc in ivy (global) mode.
Bundle sizes:
hello_world - 3.0 kB
todo - 14.7 kB

This change makes @angular/compiler more tree-shakeable by changing
an enum to a const enum and by getting rid of a top-level map that
the tree-shaker was seeing as a reference which caused r3_identifiers
to be retained.
This drops a few hundred bytes of JS from tree-shaken ngtsc compiled
apps.

The js_expected_symbol_test implementation extracts symbols names
from a rollup iife bundle. Previously, it only handled the case
with a simple 'var bundle = ...;' statement.
Sometimes, rollup produces a more complex bundle, where the 'bundle'
variable is not the only top-level variable declared in the same
declaration statement. This commit patches the symbol exctractor
to support this more complex case.
Additionally, when the symbol test fails, it prints a command to
accept the symbol diff. This command needs to include the
--define=compile flag to ensure the diff is applied in the same
compile mode as the test was run.

Currently ngtsc does not compile @Pipe. This has a side effect
of not removing the @Pipe decorator.
This adds a dummy DecoratorHandler that compiles @Pipe into an
empty ngPipeDef. Eventually this will be replaced with a full
implementation, but for now this solution allows compield code
to be tree-shaken properly.

Previously the repo was depending on an old version of build optimizer.
This change updates to the latest (an RC release in the CLI package).
Additionally, this changes the behavior of ng_rollup_bundle to apply
the optimizer to ngtsc compiled code, and configures it to treat the
@angular/compiler package as side-effect-free.
This results in a substantial size reduction of ngtsc compiled code.

Previously ngtsc removed the class-level decorators (@Component,
etc) but left all the ancillary decorators (@Input, @Optional,
etc).
This changes the transform to descend into the members of decorated
classes and remove any Angular decorators, not just the class-level
ones.
PR Close#24677
@angular/core is unique in that it defines the Angular decorators
(@Component, @Directive, etc). Ordinarily ngtsc looks for imports
from @angular/core in order to identify these decorators. Clearly
within core itself, this strategy doesn't work.
Instead, a special constant ITS_JUST_ANGULAR is declared within a
known file in @angular/core. If ngtsc sees this constant it knows
core is being compiled and can ignore the imports when evaluating
decorators.
Additionally, when compiling decorators ngtsc will often write an
import to @angular/core for needed symbols. However @angular/core
cannot import itself. This change creates a module within core to
export all the symbols needed to compile it and adds intelligence
within ngtsc to write relative imports to that module, instead of
absolute imports to @angular/core.

Classes that are injectable often have constructors that should not be
called by the application developer. It is the responsibility of the
injector to instantiate the class and the constructor often contains
private implementation details that may need to change.
This commit removes constructors from the docs for API items that are
both:
a) Marked with an injectable decorator (e.g. Injectable, Directive,
Component, Pipe), and
b) Have no constructor description
This second rule allows the developer to override the removal if there
is something useful to say about the constructor.
Note that "normal" classes such as `angimations/HttpHeaders` do not have
their constructor removed, despite (at this time) having no description.
