We should only generate the `providedIn` property in injectable
defs if it has a non-null value. `null` does not communicate
any information to the runtime that isn't communicated already
by the absence of the property.
This should give us some modest code size savings.

With this change we fix the logic to detect if a package is installed, removing a package and add a package by using the CLI schematic helpers.
Also we save `@angular/bazel` package directly as a `devDependency` when doing `ng-add`.

For injectables, we currently generate a factory function in the
injectable def (prov) that delegates to the factory function in
the factory def (fac). It looks something like this:
```
factory: function(t) { return Svc.fac(t); }
```
The extra wrapper function is unnecessary since the args for
the factory functions are the same. This commit changes the
compiler to generate this instead:
```
factory: Svc.fac
```
Because we are generating less code for each injectable, we
should see some modest code size savings. AIO's main bundle
is about 1 KB smaller.

The ViewEngine translation extractor does not convert `-` to `_` for
placeholders that represent custom elements. For example `<app-component>`
gets converted to placeholders like `START_TAG_APP-COMPONENT`.
In `$localize` placeholders are expected to be snake-case, not kebab-case.
So we must normalize them when parsing a translation file that might have
been created via the View Engine translation extractor.
The `$localize` extraction code will normalize these placeholders when
creating translation files in the first place.

Various targets have their template type-checking disabled in the past.
There is no reason for this any more.
The only target that was tricky was packages/examples/core:core_examples
which was quite broken and I had to fix it up.
Template typechecking is still disabled under blaze, see FW-1753 for more
info.

due to an unfortunate condition in 168abc6d6f/packages/compiler-cli/src/ngtsc/program.ts (L430-L434) the typechecking has been disabled when running under bazel + ivy.
As far as I can tell the ivyTemplateTypeCheck flag is now obsolete, so removing this
code from ng_module.bzl is desirable. I'll send a separate PR to remove the flag completely.

The missing-injectable migration has been updated to handle a breaking change that is
unrelated to missing ´@Injectable` decorators. Though, the breaking change will be handled
as part of this migration since we did not want to create another migration (with all the boilerplate etc.)
The guide has been already updated to reflect the new pattern the migration handles, but we
should also rename the title of the guide to something that also mentions the other pattern.
Not renaming the guide URL since it is referenced in past releases and it's safer to keep the old
URL. The important thing is to change the actual rendered title.

If a Component or Directive is not part of any NgModule, the language
service currently produces an error message. This should not be an
error. Instead, it should be a suggestion.
This PR removes `ng.DiagnosticKind`, and instead reuses
`ts.DiagnosticCategory`.

The language service incorrectly reports an error if it fails to find
NgModule metadata for a particular Component / Directive. In many cases,
the use case is legit, particularly in test.
This commit removes such diagnostic message and cleans up the interface
for `TypeScriptHost.getTemplateAst()`.

Currently, variables of an unknown type in an `*ngFor` expression are
refined to have the type of the iterable binding of the `*ngFor`
expression. Unfortunately, this is a bug for variables aliasing
[values exported by
`*ngFor`](https://angular.io/api/common/NgForOf#local-variables),
including `index` and `first`, because they are also given the type of
the binding expression, but they are not of the binding type. For
example, in
```typescript
@Component({
selector: 'test',
template: `
<div *ngFor="let hero of heroes; let i = index; let isFirst = first">
{{ hero }}
</div>
`
})
export class TestComponent {
heroes: Hero[];
}
```
The local variables `i` and `isFirst` are determined to have a type of
`Hero`, when actually their types are `number` and `boolean`,
respectively.
This commit fixes this bug by checking if the value of a variable in an
`*ngFor` expression is known to be an export and assigning the variable
the type of that export value. Only if the variable does not alias an
export is it typed with the binding value of the `*ngFor` expression.

Previously, some RxJS-related examples (which are not proper Angular apps) were not
tested on CI as part of the `example-e2e` npm script. This meant that the examples
could get out-of-date or contain compile errors without as noticing.
This commit ensures that the `example-e2e` script picks up these examples and checks
that they compile successfully.
Partly addresses #28017.

This allows us to update the version of the package in a single place for all tests.
Notable exemption of this is aio which currently doesn't depend on anything installed in the root.

Previously, the Angular AOT compiler would always add a
`ɵprov` to injectables. But in ngcc this resulted in duplicate `ɵprov`
properties since published libraries already have this property.
Now in ngtsc, trying to add a duplicate `ɵprov` property is an error,
while in ngcc the additional property is silently not added.

Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time. This commit updates the code to avoid the second check for AOT-compiled components by checking whether `schemas` information is present in a logic that executes the unknown element check.

the package.json in these tests points to file:dist/packages-dist which
is not materialized on renovate-bot, so the bot freaks out and fails to
update the lock files.
This means that the bot currently just opens up PRs that can't be merged.
Example: https://github.com/angular/angular/pull/34071
(In the past this worked nicely because we didn't keep the yarn.lock files
in the git repo for these projects, but that had a problem with unpined
depenedencies and undeterministic build/test runs).
For now it's better to disable the bot by removing all the package.jsons
from the config. We should revisit this in the future have the bot update
the root package.json instead.

When creating synthesized tagged template literals, one must provide both
the "cooked" text and the "raw" (unparsed) text. Previously there were no
good APIs for creating the AST nodes with raw text for such literals.
Recently the APIs were improved to support this, and they do an extra
check to ensure that the raw text parses to be equal to the cooked text.
It turns out there is a bug in this check -
see https://github.com/microsoft/TypeScript/issues/35374.
This commit works around the bug by synthesizing a "head" node and morphing
it by changing its `kind` into the required node type.

With Angular CLI version 9 RC 3 we can run a single migration for a package using the name of the migration schematic.
We need to pass the schematic name as a value to the `migrate-only` option.
Ex:
```
ng update @angular/core --migrate-only migration-v9-undecorated-classes-with-di
```
See: https://github.com/angular/angular-cli/pull/16174
