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.

Currently the `DebugElement.listeners` array are retained after the node is destroyed. This means that they'll continue to fire through `triggerEventHandler` and can cause memory leaks. This has already been fixed in Ivy, but these changes fix it in ViewEngine for consistency.

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

Fixes Ivy throwing an error when something is passed in as a `forwardRef` into `@Injectable`'s `useClass` option. The error was being thrown, because we were trying to get the provider factory off of the wrapper function, rather than the value itself.

`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.

This commit fixes a bug where we assumed all dynamically created
components would have tag-name selectors, so we passed through the
"tag name" to the renderer as the first index of the selector. For
components with attribute selectors, the tag name would be "", so
the renderer would try to create an element with tag name "" and
throw. Now we default to a "div" element the same way that View
Engine did.

This switches all Angular targets to be built with the same Angular compiler architecture (c.n. Ivy) that the Angular indexer uses. This eliminates issues with cross-references to transitive dependencies not being generated because of the way such dependencies are loaded by the legacy compiler arch.

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.

Introduces a new migration schematic for adding the "@Injectable()"
decorator to provider classes which are currently not migrated. Previously
in ViewEngine, classes which are declared as providers sometimes don't
require the "@Injectable()" decorator
(e.g. https://stackblitz.com/edit/angular-hpo7gw)
With Ivy, provider classes need to be explicitly decorated with
the "@Injectable()" decorator if they are declared as providers
of a given module. This commit introduces a migration schematic
which automatically adds the explicit decorator to places where
the decorator is currently missing.
The migration logic is designed in a CLI devkit and TSlint agnostic
way so that we can also have this migration run as part of a public
CLI migration w/ `ng update`. This will be handled as part of a follow-up to reiterate on console output etc.

The way the `ComponentFactory.create` is set up at the moment is that if a `rootSelectorOrNode` is passed in, the root context will be injected instead of creating dedicated one for the component. As far as I can tell, there doesn't seem to be a reason to do this and nothing seems to break because of it. These changes switch to always create the root context.

In ViewEngine nodes that were inserted through `Renderer2` would also be picked up by `DebugNode.query` and `DebugNode.queryAll`. This worked because everything in ViewEngine went through `Renderer2` and `DebugRenderer2` in dev mode which was able to keep track of the child nodes as they're being inserted. This no longer works in Ivy, because we don't use `DebugRenderer2` and debug nodes work a little differently. These changes work around the issue by walking the DOM as the logical tree is being walked and looking for matches. Note that this is __not__ optimal, because we're walking similar trees multiple times. ViewEngine could do it more efficiently, because all the insertions go through Renderer2, however that's not the case in Ivy. This approach is being used because:
1. Matching the ViewEngine behavior would mean potentially introducing a depedency from `Renderer2` to Ivy which could bring Ivy code into ViewEngine.
2. We would have to make `Renderer3` "know" about debug nodes.
3. It allows us to capture nodes that were inserted directly via the DOM.

This commit updates the `_clone` function of the `_ApplySourceSpanTransformer` class, where the for-in loop was used, resulting in copying from prototype to own properties, thus consuming more memory. Prior to NodeJS 12 (V8 versions before 7.4) there was an optimization that was improving the situation and since that logic was removed in favor of other optimizations, the situation with memory consumption caused by the for-in loop got worse. This commit adds a check to make sure we copy only own properties over to cloned object.
Closes#31627.
