While creating FESM files, rollup usually drops all unused symbols.
All *__POST_R3__ are unused unless ngcc rewires stuff. To prevent this DCE
we reexport them as private symbols. If ngcc is not used, these symbols will
be dropped when we optimize an application bundle.

Prior to this change, we were unable to match directives using `ng-template` tags (for example the following selector would not work even though there might be some <ng-template>s in a template: `ng-template[directiveA]`. As a result, that broke some components that relies on such selectors to work. In order to resolve the problem, we now pass tag name to the `template` instruction (where we passed `null` before) and this tag name is used for matching at runtime. This update should also help support projecting containers, because the tag name is required to properly match such elements.

A surprising interaction with the MagicString library caused inserted
Ivy definitions to be dropped during the removal of decorators, iff all
decorators on the class could be removed. In that case, the removal
location corresponds with the exact location where Ivy definitions were
inserted into.
This commit moves the removal of decorators to occur before Ivy
definitions are inserted. This effectively avoids the problem, as later
inserted text fragments will be retained by MagicString.

All the tests in `packages/core/test/view/` are specific to the `ViewEngine` and shouldn't run for ivy. This PR introduces a new BUILD.bazel file to run those tests separately.

If a template contains specific TypeScript syntax, such as a non-null
assertion, the code that is emitted from ngcc into a JavaScript bundle
should not retain such syntax as it is invalid in JS.
A full-blown TypeScript emit of a complete ts.SourceFile would be
required to be able to emit JS and possibly downlevel into a lower
language target, which is not an option for ngcc as it currently
operates on partial ASTs, not full source files.
Instead, ngtsc no longer produces TypeScript specific syntax in the first
place, such that TypeScript print logic will only generate JS code.

In Ivy, a pure call to `setClassMetadata` is inserted to retain the
information that would otherwise be lost while eliding the Angular
decorators. In the past, the Angular constructor decorators were
wrapped inside of an anonymous function which was only evaluated once
`ReflectionCapabilities` was requested for such metadata. This approach
prevents forward references from inside the constructor parameter
decorators from being evaluated before they are available.
In the `setClassMetadata` call, the constructor parameters were not wrapped
within an anonymous function, such that forward references were evaluated
too early, causing runtime errors.
This commit changes the `setClassMetadata` call to pass the constructor
parameter decorators inside of an anonymous function again, such that
forward references are not resolved until requested by
`ReflectionCapabilities`, therefore avoiding the early reads of forward refs.

With ngcc's ability to fixup pre-Ivy ModuleWithProviders such that they
include a reference to the NgModule type, the type may become a qualified
name:
```
import {ModuleWithProviders} from '@angular/core';
import * as ngcc0 from './module';
export declare provide(): ModuleWithProviders<ngcc0.Module>;
```
ngtsc now takes this situation into account when reflecting a
ModuleWithProvider's type argument.

Currently the `ViewRef.destroy` method assumes that its index inside the view container will always be valid, however if it has been removed already, it'll be -1 which will throw an error.
The error manifested itself in one of the unit tests where a view had been detached during the test and then `TestBed` attempted to destroy its `ComponentRef` which ended threw an `Error during cleanup of component`.

Navigating to a route such as `/users`, you may get redirected to `/login`. Previously, if you go then route to `/users` again the URL will end up showing `/users` after the second redirect. This only happened in `UrlUpdateStrategy="eager"`. This is now fixed so after the second redirect, the URL shows the correct page.

Closure Compiler doesn't allow non-goo.getMsg const names to start with `MSG_`, so we should use different prefix for const that references a result of the `i18nPostprocess` fn invocation. With this update we also append file-based prefix to i18n constants (via $$ postfix) to ensure the names are unique across codebase of a project (otherwise it might lead to errors while compiling a project with Closure Compiler).

In order to keep the bazel bin directory as clean as possible, we should not write definition files that are not relevant to a `ng_package` to an undesired location in the bazel bin directory. This currently just happens because we only filter out external definition files while we also should filter out definitions that aren't just in the current package.
The `packager.ts` file currently tries to write these files to the package, but fails because those are not inside of the current package. So the logic to create a relative path for the file fails, and the definition will be copied to a location like:
```js
// Notice the double "bazel-out" here.
C:\Users\Paul\_bazel_Paul\kn4tsvyh\execroot\angular_material\bazel-out\x64_windows-fastbuild\bin\src\bazel-out\x64_windows-fastbuild\bin\src\cdk
```
[See logic that causes this](https://github.com/angular/angular/blob/4f9374951d67c75f67a31c110bd61ab72563db7d/packages/bazel/src/ng_package/packager.ts#L105-L124) (nothing wrong with that logic because it assumes that only paths from within the package are passed to it)
