This commit changes the emit order of ngcc when a class has multiple static
fields being assigned. Previously, ngcc would emit each static field
followed immediately by any extra statements specified for that field. This
causes issues with downstream tooling such as build optimizer, which expects
all of the static fields for a class to be grouped together. ngtsc already
groups static fields and additional statements. This commit changes ngcc's
ordering to match.

If a project being built with ngtsc has no templates to check, then ngtsc
previously generated an empty typecheck file. This seems to trigger some
pathological behavior in TS where the entire user program is re-checked,
which is extremely expensive. This likely has to do with the fact that the
empty file is not considered an ES module, meaning the module structure of
the program has changed.
This commit causes an export to be produced in the typecheck file regardless
of its other contents, which guarantees that it will be an ES module. The
pathological behavior is avoided and template type-checking is fast once
again.

In #31426 a fix was implemented to render namespaced decorator imports
correctly, however it turns out that the fix only worked when decorator
information was extracted from static properties, not when using
`__decorate` calls.
This commit fixes the issue by creating the decorator metadata with the
full decorator expression, instead of only its name.

An identifier may become repeated when bundling multiple source files
into a single bundle, so bundlers have a strategy of suffixing non-unique
identifiers with a suffix like $2. Since ngcc operates on such bundles,
it needs to process potentially suffixed identifiers in their canonical
form without the suffix. The "ngx-pagination" package was previously not
compiled fully, as most decorators were not recognized.
This commit ensures that identifiers are first canonicalized by removing
the suffix, such that they are properly recognized and processed by ngcc.

Any decorator information present in TypeScript is emitted into the
generated JavaScript sources by means of `__decorate` call. This call
contains both the decorators as they existed in the original source
code, together with calls to `tslib` helpers that convey additional
information on e.g. type information and parameter decorators. These
different kinds of decorator calls were not previously distinguished on
their own, but instead all treated as `Decorator` by themselves. The
"decorators" that were actually `tslib` helper calls were conveniently
filtered out because they were not imported from `@angular/core`, a
characteristic that ngcc uses to drop certain decorators.
Note that this posed an inconsistency in ngcc when it processes
`@angular/core`'s UMD bundle, as the `tslib` helper functions have been
inlined in said bundle. Because of the inlining, the `tslib` helpers
appear to be from `@angular/core`, so ngcc would fail to drop those
apparent "decorators". This inconsistency does not currently cause any
issues, as ngtsc is specifically looking for decorators based on their
name and any remaining decorators are simply ignored.
This commit rewrites the decorator analysis of a class to occur all in a
single phase, instead of all throughout the `ReflectionHost`. This
allows to categorize the various decorate calls in a single sweep,
instead of constantly needing to filter out undesired decorate calls on
the go. As an added benefit, the computed decorator information is now
cached per class, such that subsequent reflection queries that need
decorator information can reuse the cached info.

nodejs rules 0.34.0 now includes protractor_web_test_suite rule (via new @bazel/protractor rule) so we switch to that location for that rule in this PR so that /packages/bazel/src/protractor can be removed in a future PR
this PR also brings in node toolchain support which was released in nodejs rules 0.33.0. this is a prerequisite for RBE for mac & windows users
bazel schematics also updated with the same. @bazel/bazel 0.28.1 npm package includes transitive dep on hide-bazel-files so we're able to remove an explicit dep on that as well.

`TemplateVisitor#visitBoundAttribute` currently has to invoke visiting
expressions manually (this is fixed in #31813). Previously, it did not
bind `targetToIdentifier` to the visitor before deferring to the
expression visitor, which breaks the `targetToIdentifier` code. This
fixes that and adds a test to ensure the closure processed correctly.
This change is urgent; without it, many indexing targets in g3 are
broken.

The type check blocks (TCB) that ngtsc generates for achieving type
checking of Angular templates needs to be annotated with positional
information in order to translate TypeScript's diagnostics for the TCB
code back to the location in the user's template. This commit augments
the TCB by attaching trailing comments with AST nodes, such that a node
can be traced back to its source location.

Currently we always generate the `read` parameter for the view and content query instructions, however since most of the time the `read` parameter won't be set, we'll end up generating `null` which adds 5 bytes for each query when minified. These changes make it so that the `read` parameter only gets generated if it has a value.

Extend indexing API interface to provide information about used
directives' selectors on template elements. This enables an indexer to
xref element attributes to the directives that match them.
The current way this matching is done is by mapping selectors to indexed
directives. However, this fails in cases where the directive is not
indexed by the indexer API, like for transitive dependencies. This
solution is much more general.

When analyzing components, directives, etc we capture its base class.
Previously this assumed that the code is in TS format, which is not
always the case (e.g. ngcc).
Now this code is replaced with a call to
`ReflectionHost.getBaseClassExpression()`, which abstracts the work
of finding the base class.

When injecting a `ChangeDetectorRef` into a pipe, the expected result is that the ref will be tied to the component in which the pipe is being used. This works for most cases, however when a pipe is used inside a property binding of a component (see test case as an example), the current `TNode` is pointing to component's host so we end up injecting the inner component's view. These changes fix the issue by only looking up the component view of the `TNode` if the `TNode` is a parent.

We currently have a handwritten version of the Ivy directive def for NgClass so
we can switch between Ivy and View Engine behavior. This generated code needs to
be kept up-to-date with what the Ivy compiler generates.
PR 30742 recently changed `classMap` such that it now requires allocation of
host binding slots. This means that the `allocHostVars()` function must be
called in the NgClass directive def to match compiler output, but the
handwritten directive def was not updated. This caused a bug where NgClass
was inappropriately overwriting data for other directives because space was
not allocated for its values.

Currently, template expressions and statements have their location
recorded relative to the HTML element they are in, with no handle to
absolute location in a source file except for a line/column location.
However, the line/column location is also not entirely accurate, as it
points an entire semantic expression, and not necessarily the start of
an expression recorded by the expression parser.
To support record of the source code expressions originate from, add a
new `sourceSpan` field to `ASTWithSource` that records the absolute byte
offset of an expression within a source code.

Versions of CLI prior to angular/angular-cli@0e339ee did not expose the host.getModifiedResourceFiles() method.
This meant that null was being passed through to the IncrementalState.reconcile() method
to indicate that there were either no changes or the host didn't support that method.
This commit fixes a bug where we were checking for undefined rather than null when
deciding whether any resource files had changed, causing a null reference error to be thrown.
This bug was not caught by the unit testing because the tests set up the changed files
via a slightly different process, not having access to the CompilerHost, and these test
were making the erroneous assumption that undefined indicated that there were no
changed files.
