Currently if one of the project targets could not be analyzed
due to AOT compiler program failures, we gracefully proceed
with the migration. This is expected, but we should not
print a message at the end of the migration that the migration
was _successful_. The migration was only done partially, hence
it's potentially incomplete and we should make it clear that once
the failures are resolved, the migration should be re-run.

Also removes `build:remote --spawn_strategy=remote` from .bazelrc. It seems that with Bazel 1.0.0 setting `--incompatible_list_based_execution_strategy_selection=false` no longer works around the issue with npm_package that it did when it was added. The error that was originally observed has returned after updating to Bazel 1.0.0:
```

This commit removes both `—incompatible_list_based_execution_strategy_selection=false` as well as `build:remote --spawn_strategy=remote` which means that Bazel will do the default behavior of picking the first available strategy from the default list, which is `remote,worker,sandboxed,local`.

Note: the @angular/bazel schematic now appends the package.json "script" field with 'ngcc --properties es2015 browser module main'. If there is an existing script field with ngcc then the schematic modifies it in place removing `--first-only` and `--create-ivy-entry-points`.
ViewEngine sources under node_modules need to be updated in-place for Bazel as it does not know how to use the `__ivy__` entry points that are created by the non-bazel `ngcc` command that is added to "scripts" :`ngcc --properties es2015 browser module main --first-only --create-ivy-entry-points`.

Prior to this commit, i18n logic which ensures that elements removed in a translation are also removed in DOM, didn't take into account the fact that elements may have local refs. As a result, remove operation failed, since there is no corresponding tNode found. This commit updates the logic to skip all local refs while going though the list of nodes to ensure that DOM matches elements present in translation.

Adds a `replacementSpan` field on a completion that will allow typed
text to be replaced with the suggested completion value if a user
selects the completion. Previously, the completion value would simply be
appended to the text already typed. E.g. if we had
```
{{ti}}

typed in a template and `title` was recommended as a completion and
selected, the template would become
```
{{tititle}}

With `replacementSpan`, the original text `ti` will be replaced for
`title`.

`bindingIndex` stores the current location of the bindings in the
template function. Because it used to be stored in `LView` that `LView`

The `localize-translate` command line tool can now accept an array of
target locales to support the case where translation files do not
contain them. Specify this array via the `--target-locales` option.

Previously the target locale of a translation file had to be extracted
from the contents of the translation file. Therefore it was an error if
the translation file did not provide a target locale.
Now an array of locales can be provided via the `translationFileLocales`
option that overrides any target locale extracted from the file.
This allows us to support translation files that do not have a target
locale specified in their contents.

Currently the `missing-injectable` migration seems to add
`@Injectable()` to third-party classes in type definitions.
This not an issue in general since we do not generate broken code
by inserting a decorator into a type definition file. Though, we can
avoid adding the decorator since it won't have any effect and in
general we should not write to non source files of the compilation unit.

We should not migrate the reference from `useExisting`. This is because
developers can only use the `useExisting` value as a token. e.g.
```ts
@NgModule({
providers: [
{provide: AppRippleConfig, useValue: rippleOptions},
{provide: MAT_RIPPLE_OPTIONS, useExisting: AppRippleConfig},
]
})
export class AppModule {}
```
In the case above, nothing should be decorated with `@Injectable`. The
`AppRippleConfig` class is just used as a token for injection.

Currently the migration is unable to migrate instances where
the provider definition uses `forwardRef`. Since this is a

the static evaluation that is used by the ngtsc annotations.

Removes `ngBaseDef` from the compiler and any runtime code that was still referring to it. In the cases where we'd previously generate a base def we now generate a definition for an abstract directive.
PR Close#33264
For abstract directives, i.e. directives without a selector, it may
happen that their constructor is called explicitly from a subclass,
hence its parameters are not required to be valid for Angular's DI
purposes. Prior to this commit however, having an abstract directive
with a constructor that has parameters that are not eligible for
Angular's DI would produce a compilation error.
A similar scenario may occur for `@Injectable`s, where an explicit
`use*` definition allows for the constructor to be irrelevant. For
example, the situation where `useFactory` is specified allows for the
constructor to be called explicitly with any value, so its constructor
parameters are not required to be valid. For `@Injectable`s this is
handled by generating a DI factory function that throws.
This commit implements the same solution for abstract directives, such
that a compilation error is avoided while still producing an error at
runtime if the type is instantiated implicitly by Angular's DI
mechanism.

In Angular View Engine, there are two kinds of decorator inheritance:
1) both the parent and child classes have decorators
This case is supported by InheritDefinitionFeature, which merges some fields
of the definitions (such as the inputs or queries).
2) only the parent class has a decorator
If the child class is missing a decorator, the compiler effectively behaves
as if the parent class' decorator is applied to the child class as well.
This is the "undecorated child" scenario, and this commit adds a migration
to ngcc to support this pattern in Ivy.
This migration has 2 phases. First, the NgModules of the application are
scanned for classes in 'declarations' which are missing decorators, but
whose base classes do have decorators. These classes are the undecorated
children. This scan is performed recursively, so even if a declared class
has a base class that itself inherits a decorator, this case is handled.
Next, a synthetic decorator (either @Component or @Directive) is created
on the child class. This decorator copies some critical information such
as 'selector' and 'exportAs', as well as supports any decorated fields
(@Input, etc). A flag is passed to the decorator compiler which causes a
special feature `CopyDefinitionFeature` to be included on the compiled
definition. This feature copies at runtime the remaining aspects of the
parent definition which `InheritDefinitionFeature` does not handle,
completing the "full" inheritance of the child class' decorator from its
parent class.
PR Close#33362
This commit adds CopyDefinitionFeature, which supports the case where an
entire decorator (@Component or @Directive) is inherited from parent to
child.
The existing inheritance feature, InheritDefinitionFeature, supports merging
of parent and child definitions when both were originally present. This
merges things like inputs, outputs, host bindings, etc.
CopyDefinitionFeature, on the other hand, compensates for a definition that
was missing entirely on the child class, by copying fields that aren't
ordinarily inherited (like the template function itself).
This feature is intended to only be used as part of ngcc code generation.

When upgrading an Angular application to a new version using the Angular
CLI, built-in schematics are being run to update user code from
deprecated patterns to the new way of working. For libraries that have
been built for older versions of Angular however, such schematics have
not been executed which means that deprecated code patterns may still be
present, potentially resulting in incorrect behavior.
Some of the logic of schematics has been ported over to ngcc migrations,
which are automatically run on libraries. These migrations achieve the
same goal of the regular schematics, but operating on published library
sources instead of used code.
PR Close#33362
Previously, the (currently disabled) undecorated parent migration in
ngcc would produce errors when a base class could not be determined
statically or when a class extends from a class in another package. This
is not ideal, as it would cause the library to fail compilation without
a workaround, whereas those problems are not guaranteed to cause issues.
Additionally, inheritance chains were not handled. This commit reworks
the migration to address these limitations.
PR Close#33362
In ngcc's migration system, synthetic decorators can be injected into a
compilation to ensure that certain classes are compiled with Angular
logic, where the original library code did not include the necessary
decorators. Prior to this change, synthesized decorators would have a
fake AST structure as associated node and a made-up identifier. In
theory, this may introduce issues downstream:
1) a decorator's node is used for diagnostics, so it must have position
information. Having fake AST nodes without a position is therefore a
problem. Note that this is currently not a problem in practice, as
injected synthesized decorators would not produce any diagnostics.
2) the decorator's identifier should refer to an imported symbol.
Therefore, it is required that the symbol is actually imported.
Moreover, bundle formats such as UMD and CommonJS use namespaces for
imports, so a bare `ts.Identifier` would not be suitable to use as
identifier. This was also not a problem in practice, as the identifier
is only used in the `setClassMetadata` generated code, which is omitted
for synthetically injected decorators.
To remedy these potential issues, this commit makes a decorator's
identifier optional and switches its node over from a fake AST structure
to the class' name.

A class that is provided as Angular service is required to have an
`@Injectable()` decorator so that the compiler generates its injectable
definition for the runtime. Applications are automatically migrated
using the "missing-injectable" schematic, however libraries built for
older version of Angular may not yet satisfy this requirement.
This commit ports the "missing-injectable" schematic to a migration that
is ran when ngcc is processing a library. This ensures that any service
that is provided from an NgModule or Directive/Component will have an
`@Injectable()` decorator.

ngcc has an internal cache of computed decorator information for
reflected classes, which could previously be mutated by consumers of the
reflection host. With the ability to inject synthesized decorators, such
decorators would inadvertently be added into the array of decorators
that was owned by the internal cache of the reflection host, incorrectly
resulting in synthesized decorators to be considered real decorators on
a class. This commit fixes the issue by cloning the cached array before
returning it.

The template type checking abilities of the Ivy compiler are far more
advanced than the level of template type checking that was previously
done for Angular templates. Up until now, a single compiler option
called "fullTemplateTypeCheck" was available to configure the level
of template type checking. However, now that more advanced type checking
is being done, new errors may surface that were previously not reported,
in which case it may not be feasible to fix all new errors at once.
Having only a single option to disable a large number of template type
checking capabilities does not allow for incrementally addressing newly
reported types of errors. As a solution, this commit introduces some new
compiler options to be able to enable/disable certain kinds of template
type checks on a fine-grained basis.
