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`.

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](4f9374951d/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)

The pure functions in host bindings change was merged after the change in
host binding instructions, so it had a new test that wasn't yet updated
with the new generated code. This commit updates the new test.
PR Close#27605
Previously in Ivy, host bindings did not work if they shared a public name
with an Input because they used the `elementProperty` instruction as is.
This instruction was originally built for inside component templates, so it
would either set a directive input OR a native property. This is the
correct behavior for inside a template, but for host bindings, we always
want the native properties to be set regardless of the presence of an Input.
This change adds an extra argument to `elementProperty` so we can tell it to
ignore directive inputs and only set native properties (if it is in the
context of a host binding).

Prior to this update, we always returned the number of host vars defined in @Component definition as a value for `allocatePureFunctionsSlot` callback in ValueConverter. As a result, pure function arguments were not accounted for, thus leasing to incorrect slot offsets in `pureFunction` calls. Now we update and return total # of host vars, so the offsets are defined correctly.

When @angular/bazel is installed, a postinstall script is run to make sure that
the npm version is *exactly* the same as the Angular repository install by

In `ViewRef.detectChanges`, we are passing `ViewRef.context` into `detectChanges` to trigger change detection. This only makes sense for component `ViewRefs` (i.e. injected `ChangeDetectorRefs`) because with embedded views, `context` is not a component instance where the view has been monkey-patched. It's a just a normal object, so the view will be undefined.
In order to resolve this problem, we now invoke `detectChangesInternal` and also pass `LView` (to make sure we always have a view available).

Common insensitive platforms are `win32/win64` (see:
[here](3e4c5c95ab/src/compiler/sys.ts (L681-L682)))
Currently when running `bazel build packages/core --define=compile=aot`, the `compiler-cli` will throw because it cannot find the `index.ngfactory.ts` file in the compiler host. This is because the shim host wrapper is not properly generating the requested `ngfactory` file.
This happens because we call `getCanonicalFileName` that returns a path that is different to the actual program filenames that are used to construct a map of generated files. Since the generators always use the paths which are not "canonical" and pases them internally like that, we can just stop manually calling `getCanonicalFileName`.

ngfactory files have a ɵNonEmptyModule constant included if there are no
other exported factory symbols. Previously this extra export was added
dynamically in a TS transformer.
However, synthetically constructed exports don't get properly downleveled
during JS emit, and this generated constant caused issues with downstream
tests.
Instead, this commit configures the shim to always have this export to
begin with, and to filter it out if it's not required.
Testing strategy: covered by existing ngtsc_spec tests which verify the
presence of the ɵNonEmptyModule symbol.

In ngtsc, files loaded into the ts.Program have a "module name", set via
ts.SourceFile.moduleName, which ends up being written into an AMD module
name triple-slash directive in the generated .js file.
For generated shim files (ngfactories, ngsummaries) that are constructed
synthetically, there was previously no moduleName set, which caused some
issues with downstream tests.
This commit adds logic to compute and set moduleNames for both generated
ngfactory and ngsummary shims.

so declarations which arrive via more than one module import are coalesced.

This commit allows //packages/bazel/test/ngc-wrapped/... tests to run
under Ivy mode. To get them to pass, it addresses a problem with the
way the tests are configured: both test targets have sloppy .d.ts
dependencies configured, leading to many type errors being generated
in TypeScript for the .d.ts files.
Due to the way ngc directs TypeScript emit, it avoids type-checking
.d.ts files and thus this issue does not surface. ngtsc does a whole-
program emit which results in full .d.ts type-checking by default,
catching this configuration issue.
To fix this, skipLibCheck is added to the tsconfig.jsons for these
tests, which tells TypeScript to skip type-checking of the .d.ts files,
avoiding this problem in a similar way to ngc.

The method `ts.CompilerHost.directoryExists` is optional, and was not

of directoryExists() to the shim.
A test is also added which verifies typeRoots behavior works when shims

Previously the ngfactory shim generator in ngtsc would always write two
imports in the factory file shims:
1) an import to @angular/core
2) an import to the base file

to cause issues downstream.
This commit changes the generated shim so if there are no exports in the

This option means guards and resolvers will ignore changes to matrix parameters. Guards and resolvers will be rerun when the path changes, when path parameters change, or when query parameters change.
The primary use case for such a mode is when updating the UI and getting the URL to be in sync with local changes. For example, if displaying a sortable table, changing the sort direction is often handled by the table itself. But you would want to update the URL to be in sync with what's being displayed to the user. As long as the table sort direction is stored as a matrix parameter, you can use this option to update the URL without causing the overhead of re-running guards and resolvers.

These changes return a new `ViewRef` in order to match the original behavior.
These changes also add the same errors as `ViewEngine` when attempting to attach a view that is attached already. This was the original goal of this PR, however it ended up uncovering the issues with the `ViewRef`.
