We should make this configurable so that the node injector is tree shaken when
directives do not need to be published.

This commit adds basic support for <ng-container> - most of the
functionality should work as long as <ng-container> is a child of
a regular element.

Before the `ngDevMode` had to be set explicitly or it would throw
an exception at runtime. This changes it so that if `ngDevModu` is
`undefined` than we default to `ngDevMode = true`. In other words
unless the developer has explicitly asked to make a prodution build
by setting `ngDevMode = false` as compilation constant, the default
is `ngDevMode = true`.
This also fixes a minor bug where the setup code would read
`global['ngDevMode']` but all other code would read `global.ngDevMode`.
This would cause issues with closure compiler since the
reading of the `ngDevMode` must be consistent.

Update XMB placeholders(<ph>) to include the original value on top of an
example. Placeholders can by definition have one example(<ex>) tag and a
text node. The text node is used by TC as the "original" value from the
placeholder, while the example should represent a dummy value.
For example: <ph name="PET"><ex>Gopher</ex>{{ petName }}</ph>.
This change makes sure that we have the original text, but it *DOES NOT*
make sure that the example is correct. The example has the same wrong
behavior of showing the interpolation text rather than a useful
example.
No breaking changes, but tools that depend on the previous behavior and
don't consider the full XMB definition may fail to parse the XMB.

- `directiveInjector()` is used to inject anything in the directive / component
/ pipe factories so adding `InjectionToken<T>` as a supported token type.
- `getOrCreateInjectable()` should search first in the node injector tree and
then in the module injector tree (was either or before the PR).

When ngtsc encounters a reference to a type (for example, a Component
type listed in an NgModule declarations array), it traces the import
of that type and attempts to determine the best way to refer to it.
In the event the type is defined in the same file where a reference
is being generated, the identifier of the type is used. If the type
was imported, ngtsc has a choice. It can use the identifier from the
original import, or it can write a new import to the module where the
type came from.
ngtsc has a bug currently when it elects to rely on the user's import.
When writing a .d.ts file, the user's import may have been elided as
the type was not referred to from the type side of the program. Thus,
in .d.ts files ngtsc must always assume the import may not exist, and
generate a new one.
In .js output the import is guaranteed to still exist, so it's
preferable for ngtsc to continue using the existing import if one is
available.
This commit changes how @angular/compiler writes type definitions, and
allows it to use a different expression to write a type definition than
is used to write the value. This allows ngtsc to specify that types in
type definitions should always be imported. A corresponding change to
the staticallyResolve() Reference system allows the choice of which
type of import to use when generating an Expression from a Reference.

Fixes#25018.
Instantiating a NgModuleRef from NgModuleFactory reuses the NgModuleDefinition if it is already present. However the NgModuleDefinition has a providers array which modified when tree shakable providers are instantiated. This corrupts the provider definitions the next time the same factory is used to create a new NgModuleRef - Two provider definitions can end up with the same index anf the injector could potentially return a completely wrong object for a provider token.
This scenario is more likely on the server where the same NgModuleFactory is reused across requests.
The fix clones the cached NgModuleDefinition so that any tree shakable providers added later do not affect the cached copy.

Ivy definition types have a generic type which specifies the return
type of the factory function. For example:
static ngDirectiveDef<NgForOf, '[ngFor][ngForOf]'>
However, in this case NgForOf itself has a type parameter <T>. Thus,
writing the above is incorrect.
This commit modifies ngtsc to understand the genericness of NgForOf and
to write the following:
static ngDirectiveDef<NgForOf<any>, '[ngFor][ngForOf]'>

Previously ngtsc would use a tuple of class types for listing metadata
in .d.ts files. For example, an @NgModule's declarations might be
represented with the type:
[NgIf, NgForOf, NgClass]
If the module had no declarations, an empty tuple [] would be produced.
This has two problems.
1. If the class type has generic type parameters, TypeScript will
complain that they're not provided.
2. The empty tuple type is not actually legal.
This commit addresses both problems.
1. Class types are now represented using the `typeof` operator, so the
above declarations would be represented as:
[typeof NgIf, typeof NgForOf, typeof NgClass].
Since typeof operates on a value, it doesn't require generic type
arguments.
2. Instead of an empty tuple, `never` is used to indicate no metadata.

Previously, some of the *Def symbols were not exported or were exported
as public API. This commit ensures every definition type is in the
private export namespace.

ngInjectorDef.imports is generated from @NgModule.imports plus
@NgModule.exports. A problem arises as a result, because @NgModule
exports contain not only other modules (which will have ngInjectorDef
fields), but components, directives, and pipes as well. Because of
locality, it's difficult for the compiler to filter these out at
build time.
It's not impossible, but for now filtering them out at runtime will
allow testing of the compiler against complex applications.
