During static evaluation of expressions within ngtsc, it may occur that
certain expressions or just parts thereof cannot be statically
interpreted for some reason. The static interpreter keeps track of the
failure reason and the code path that was evaluated by means of
`DynamicValue`, which will allow descriptive errors. In some situations
however, the static interpreter would throw an exception instead,
resulting in a crash of the compilation. Not only does this cause
non-descriptive errors, more importantly does it prevent the evaluated
result from being partial, i.e. parts of the result can be dynamic if
their value does not have to be statically available to the compiler.
This commit refactors the static interpreter to never throw errors for
certain expressions that it cannot evaluate.

Using the async pipe as the very first example makes it very confusing for beginners. Most people believe that | async is required for ngFor. I would remove that part to make the example solely focused on NgFor.
PR Close#33378
Previously the compiler would crash if a pipe was encountered which did not
match any pipe in the scope of a template.
This commit introduces a new diagnostic error for unknown pipes instead.
PR Close#33454
Previously the template binder would crash when encountering an unknown
localref (# reference) such as `<div #ref="foo">` when no directive has
`exportAs: "foo"`.
With this commit, the compiler instead generates a template diagnostic error
informing the user about the invalid reference.

Before this change instantiating multiple directives on the same
host node would result in repeated RNode retrieval and patching.
This commint re-organises code around directive instance creation
so the host node processing (common to all directives) happens
once and only once.
As the additional benefit the directive instantiation logic gets
centralised in one function (at the expense of patching logic
duplication for root node).

Previously declarations that were imported via a namespace import
were given the same `bestGuessOwningModule` as the context
where they were imported to. This causes problems with resolving
`ModuleWithProviders` that have a type that has been imported in
this way, causing errors like:
```
ERROR in Symbol UIRouterModule declared in
.../@uirouter/angular/uiRouterNgModule.d.ts
is not exported from
.../@uirouter/angular/uirouter-angular.d.ts
(import into .../src/app/child.module.ts)
```
This commit modifies the `TypescriptReflectionHost.getDirectImportOfIdentifier()`
method so that it also understands how to attach the correct `viaModule` to
the identifier of the namespace import.

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:
```
ERROR: /home/circleci/ng/packages/angular_devkit/build_optimizer/BUILD:66:1: Assembling npm package packages/angular_devkit/build_optimizer/npm_package failed: No usable spawn strategy found for spawn with mnemonic Action. Your --spawn_strategy, --genrule_strategy or --strategy flags are probably too strict. Visit https://github.com/bazelbuild/bazel/issues/7480 for migration advice
```
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`. See https://github.com/bazelbuild/bazel/issues/7480 for more details.
Not updating to Bazel 1.1.0 yet due to a docker permissions CI issue that was observed on the angular repo that is unresolved. See https://github.com/angular/angular/pull/33367#issuecomment-547643246.

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`.

Now that we've replaced `ngBaseDef` with an abstract directive definition, there are a lot more cases where we generate a directive definition without a selector. These changes make it so that we don't generate the `selectors` array if it's going to be empty.

The parser was accidentally reading the `target` tag
below the `alt-trans` target and overriding the correct
`target` tag.
(This already worked in `$localize` but a test has been
added to confirm.)

Currently this repo allows Yarn between 1.17.3 and 1.18.0, whereas the components repo requires a minimum of 1.19.1 which makes it annoying to switch between repositories. These changes bump the maximum allowed Yarn version.

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.
