The `<template>` tag was deprecated in Angular v4 to avoid collisions (i.e. when
using Web Components).
This commit removes support for `<template>`. `<ng-template>` should be used
instead.

# This option is no more supported and will have no effect

Closure has a transformation which turns:
Service.ngInjectableDef = ...;
into:
Service$ngInjectableDef = ...;
This transformation obviously breaks Ivy in a major way. The solution is
to annotate the fields as @nocollapse. However, Typescript appears to ignore
synthetic comments added to a node during a transformation, so the "right"
way to add these comments doesn't work.
As an interim measure, a post-processing step just before the compiled JS is
written to disk appends the correct comments with a regular expression.

Previously the flag would only disable the check in the case we tried to use newer tsc version.
In g3 we sometimes take a while to update tsc, but as a prerequisite of that Angular needs to be
updated first. This change enables us to update Angular and use it in g3 while g3 is being update
to the required tsc. Of course extra care is required when this check is disabled, but since we
control everything in g3, it's on us to get this right.
I don't see any preexisting tests for this, and I'm not sure how to write them right now.

When the compiler generates a reference to an exported variable in the
same file, it inserts a synthetic ts.Identifier node. In CommonJS
output, this synthetic node would not be properly rewritten with an
`exports.` prefix.
This change sets the TS original node property on the synthetic node
we generate, which ensures TS knows to rewrite it in CommonJS output.

Previously the injectable compiler assumed all tree-shakeable injectables
would have dependencies that were injectables or InjectionTokens. However
old code still uses string tokens (e.g. NgUpgrade and '$injector'). Using
such tokens would cause the injectable compiler to crash.
Now, the injectable compiler can properly generate a dependency on such a
string token.

"ng update" supports having multiple packages as part of a group which should be updated together, meaning that e.g. calling "ng update @angular/core" would be equivalent to updating all packages of the group (that are part of the package.json already).
In order to support the grouping feature, the package.json of the version the user is updating to needs to include an "ng-update" key that points to this metadata.
The entire specification for the update workflow can be found here: 2e8b12a4ef/docs/specifications/update.md

inject() supports the ngInjectableDef-based configuration of the injector
(otherwise known as tree-shakeable services). It was missing from the
exported API of @angular/core, this PR adds it.
The test added here is correct in theory, but may pass accidentally due
to the decorator side-effect replacing the inject() call at runtime. An
upcoming compiler PR will strip reified decorators from the output
entirely.

InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this
requires a runtime reflection system in order to generate factories
from expressed provider declarations.
Instead, this change requires scoped InjectionTokens to provide the
factory directly (likely using inject() for the arguments), bypassing
the need for a reflection system.
Fixes#22205

@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs
in the root injector. A developer attempting to ensure that must either
also provide a module intended for placement in the root injector or target
a module known to already be in the root injector (e.g. BrowserModule).
Both of these strategies are cumbersome and brittle.
Instead, this commit adds a token APP_ROOT_SCOPE which provides a
straightforward way of targeting the root injector directly, without
requiring special knowledge of modules within it.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

Allows a directive to use the expression passed directly to a property
as a guard instead of filtering the type through a type expression.
This more accurately matches the intent of the ngIf usage of its template

Previously, this code would unconditionally add a @fileoverview
comment to generated files, and only if the contained any code at all.
However often existing fileoverview comments should be copied from the
file the generated file was originally based off of. This allows users
to e.g. include Closure Compiler directives in their original
`component.ts` file, which will then automaticallly also apply to code
generated from it.
This special cases `@license` comments, as Closure disregards directives
in comments containing `@license`.

`$any()` can now be used in a binding expression to disable type

Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.
NgIf was modified to declare an input guard on ngIf.
After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.
For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.
The template compiler will generate code similar to,
```
if (NgIf.ngIfTypeGuard(instance.person)) {
instance.person.name
}
```
to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

Closure Compiler by default will report diagnostics from type checks in
any JavaScript code, including code emitted by the Angular compiler.
Disabling `checkTypes` substantially reduces warning spam for users, and
allows them to run with stricter compiler flags (e.g. treating actual
diagnostics from user code as errors).
Closure Compiler will still type check the code and use types (where
found and correct) for optimizations.
