This commit splits apart selector_scope.ts in ngtsc and extracts the logic
into two separate classes, the LocalModuleScopeRegistry and the
DtsModuleScopeResolver. The logic is cleaned up significantly and new tests
are added to verify behavior.
LocalModuleScopeRegistry implements the NgModule semantics for compilation
scopes, and handles NgModules declared in the current compilation unit.
DtsModuleScopeResolver implements simpler logic for export scopes and
handles NgModules declared in .d.ts files.
This is done in preparation for the addition of re-export logic to solve
StrictDeps issues.

At the moment, the API extractor doesn't support local namespaced imports, this will break the generation of flat dts files. When we turn on dts bundling for this package it will break. Hence this is the ground work needed for making this package compatable with the API extractor.

During build time we remap particular property bindings, because their names don't match their attribute equivalents (e.g. the property for the `for` attribute is called `htmlFor`). This breaks down if the particular element has an input that has the same name, because the property gets mapped to something invalid.
The following changes address the issue by mapping the name during runtime, because that's when directives are resolved and we know all of the inputs that are associated with a particular element.

Prior to this change presence of HTML comments inside <ng-content> caused compiler to throw an error that <ng-content> is not empty. Now HTML comments are not considered as a meaningful content, thus no error is thrown. This behavior is now aligned in Ivy/VE.

Prior to this change absolute file paths (like `/a/b/c/style.css`) were calculated taking current component file location into account. As a result, absolute file paths were calculated using current file as a root. This change updates this logic to ignore current file path in case of absolute paths.

Prior to this change, Ivy and VE CSS resource resolution was different: in addition to specified styleUrl (with .scss, .less and .styl extensions), VE also makes an attempt to resolve resource with .css extension. This change introduces similar logic for Ivy to make sure Ivy behavior is backwards compatible.

Prior to this change, the @fileoverview annotations added by users in source files or by tsickle during compilation might have change a location due to the fact that Ngtsc may prepend extra imports or constants. As a result, the output file is considered invalid by Closure (misplaced @fileoverview annotation). In order to resolve the problem we relocate @fileoverview annotation if we detect that its host node shifted.

This change is kind of similar to #27466, but instead of ensuring that
these shims can be generated, we also need to make sure that developers
are able to also use the factory shims like with `ngc`.
This issue is now surfacing because we have various old examples which
are now also built with `ngtsc` (due to the bazel migration). On case insensitive
platforms (e.g. windows) these examples cannot be built because ngtsc fails
the app imports a generated shim file (such as the factory shim files).
This is because the `GeneratedShimsHostWrapper` TypeScript host uses
the `getCanonicalFileName` method in order to check whether a given
file/module exists in the generator file maps. e.g.
```
// Generator Map:
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts' =>
'C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ts',
// Path passed into `fileExists`
C:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
// After getCanonicalFileName (notice the **lower-case drive name**)
c:/users/paul/_bazel_paul/lm3s4mgv/execroot/angular/packages/core/index.ngfactory.ts
```
As seen above, the generator map does not use the canonical file names, as well as
TypeScript internally does not pass around canonical file names. We can fix this by removing
the manual call to `getCanonicalFileName` and just following TypeScript internal-semantics.

This change enables dts bundling for the following packages and their secondary entry points:
- @angular/animations
- @angular/elements
- @angular/http
- @angular/platform-browser
- @angular/platform-browser-dynamic
- @angular/platform-server
- @angular/platform-webworker
- @angular/platform-webworker-dynamic
- @angular/servce-worker
Dts bundling happens in `ng_module` bazel definition, hence packages such as `@angular/compiler`, `@angular/compiler-cli` and `@angular/langauge service` cannot be flattened as they use `ts_library`.
`@angular/core`, `@angular/common`, `@angular/upgrade` and `@angular/forms` will be done seperatly as it requires some changes either to their source or specs.

We previously disabled this test because we did not yet have
static query support in Ivy and the planned API would be
slightly different. Now that a static query flag is available
that works in both View Engine and Ivy, the test has been
updated to use that flag and has been turned on to run in CI.
Since the test was always unrelated to queries and was intended
to test *ngIf behavior, updating the test in this instance
seems reasonable.

This commit adds support for the `static: true` flag in `ContentChild`
queries. Prior to this commit, all `ContentChild` queries were resolved
after change detection ran. This is a problem for backwards
compatibility because View Engine also supported "static" queries which
would resolve before change detection.
Now if users add a `static: true` option, the query will be resolved in
creation mode (before change detection runs). For example:
```ts
@ContentChild(TemplateRef, {static: true}) template !: TemplateRef;
```
This feature will come in handy for components that need
to create components dynamically.

Prior to this commit, the timing of `ViewChild`/`ContentChild` query
resolution depended on the results of each query. If any results
for a particular query were nested inside embedded views (e.g.
*ngIfs), that query would be resolved after change detection ran.
Otherwise, the query would be resolved as soon as nodes were created.
This inconsistency in resolution timing had the potential to cause
confusion because query results would sometimes be available in
ngOnInit, but sometimes wouldn't be available until ngAfterContentInit
or ngAfterViewInit. Code depending on a query result could suddenly
stop working as soon as an *ngIf or an *ngFor was added to the template.
With this commit, users can dictate when they want a particular
`ViewChild` or `ContentChild` query to be resolved with the `static`
flag. For example, one can mark a particular query as `static: false`
to ensure change detection always runs before its results are set:
```ts
@ContentChild('foo', {static: false}) foo !: ElementRef;
```
This means that even if there isn't a query result wrapped in an
*ngIf or an *ngFor now, adding one to the template later won't change
the timing of the query resolution and potentially break your component.
Similarly, if you know that your query needs to be resolved earlier
(e.g. you need results in an ngOnInit hook), you can mark it as
`static: true`.
```ts
@ViewChild(TemplateRef, {static: true}) foo !: TemplateRef;
```
Note: this means that your component will not support *ngIf results.
If you do not supply a `static` option when creating your `ViewChild` or
`ContentChild` query, the default query resolution timing will kick in.
Note: This new option only applies to `ViewChild` and `ContentChild`
queries, not `ViewChildren` or `ContentChildren` queries, as those types
already resolve after CD runs.

Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.
Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.
These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.
```
src/
| lib/
| index.ts -> References the call expression using `../../di`
```
Now the metadata looks like that:
```
node_modules/
| @angular/
-- | core/
-- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
| di/
```
Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.
We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).
Fixes#28741.

Currently setting `enableIvy` to true runs a hybrid mode of `ngc` and `ngtsc`. This is counterintuitive given the name of the flag itself.
This PR makes the `true` value equivalent to the previous `ngtsc`, and `ngtsc` becomes an alias for `true`. Effectively this removes the hybrid mode as well since there's no other way to enable it.

Previously, `ngtsc` detected class inheritance in a way that only worked
in TS or ES2015 code. As a result, inheritance would not be detected for
code in ES5 format, such as when running `ngtsc` through `ngcc` to
transform old-style Angular code to ivy format.
This commit fixes it by delegating class inheritance detection to the
current `ReflectionHost`, which is able to correctly interpret the used
code format.

Accounts for schemas in when validating properties in Ivy.
This PR resolves FW-819.
A couple of notes:
* I had to rework the test slightly, in order to have it fail when we expect it to. The one in master is passing since Ivy's validation runs during the update phase, rather than creation.
* I had to deviate from the design in FW-819 and not add an `enableSchema` instruction, because the schema is part of the `NgModule` scope, however the scope is only assigned to a component once all of the module's declarations have been resolved and some of them can be async. Instead, I opted to have the `schemas` on the component definition.
