Docs examples of type `i18n` need a slightly modified version of
`polyfills.ts` that imports `@angular/localize/init`. Previously, this
file was not included in `i18n` example projects for two reasons:
- While the file was included in the `i18n` boilerplate files (at
`aio/tools/examples/shared/boilerplate/i18n/`), it was not included in
the boilerplate file list in `example-boilerplate.js`.
- The file was in the wrong location: It was located at the project root
instead of inside the `src/` directory.
This commit addresses the above issues (i.e. adds the file to the
boilerplate file list for `i18n` projects and moves the file inside the
`src/` directory).

There were some `systemjs.config.web[.build].js` files in the `systemjs`
boilerplate directory that are not used any more. In the past, these
files were used in the Plunker-based live examples, but we no longer use
Plunker for live examples.

There were two `typings.d.ts` files with SystemJS module definitions in
`aio/src/` and `aio/tools/examples/shared/boilerplate/cli/`. These are
remnants from old CLI versions that used SystemJS and are no longer
needed. For docs examples specifically, these files were never copied
over to example projects and thus not included in StackBlitz projects
and ZIP archives.
This commit removes these obsolete files.

Developer docs previously stated to use `yarn bazel test //packages/...` which attempts to test all packages with View
Engine (the default), even though not all support View Engine. This updates the doc to use `yarn test-ivy-aot` and
`yarn test-non-ivy` which tests both Ivy and View Engine while filtering out tests which are not compatible with each
renderer.

This commit refactors the way we store validators in AbstractControl-based classes:
in addition to the combined validators function that we have, we also store the original list of validators.
This is needed to have an ability to clean them up later at destroy time (currently it's problematic since
they are combined in a single function).
The change preserves backwards compatibility by making sure public APIs stay the same.
The only public API update is the change to the `AbstractControl` class constructor to extend the set
of possible types that it can accept and process (which should not be breaking).

This commit updates synthetic host property and listener instruction names to better align with other instructions.
The `ɵɵupdateSyntheticHostBinding` instruction was renamed to `ɵɵsyntheticHostProperty` (to match the `ɵɵhostProperty`
instruction name) and `ɵɵcomponentHostSyntheticListener` was renamed to `ɵɵsyntheticHostListener` since this
instruction is generated for both Components and Directives (so 'component' is removed from the name).
This PR is a followup after PR #35568.

into multiple documents. The second phase will be
a rewrite of each doc.
Specifically, this PR does the following:
- Breaks sections of the current template syntax document each into their own page.
- Corrects the links to and from these new pages.
- Adds template syntax subsection to the left side NAV which contains all the new pages.
- Adds the new files to pullapprove.

Add new type: confusing and type: use-case labels to the triage readme as well
as clarify that freq and severity are only required for type: bug/fix
PR Close#38081
Some issue reports don't really fall into any of the current buckets that count
towards triage level 2: bug/fix, feature, or refactor. Some reports are:
* working as intended but confusing - the labels might be 'type: confusing', 'comp: docs', 'comp: router'
* generally working as originally designed but a use-case could be argued for a different implementation.
This type of report is a little hard to triage; it may be neither a bug, nor feature but more of a
'type: use-case'. These may eventually turn into a bug/fix or feature, but can't necessarily be
put in those buckets immediately.

HTML is very lenient when it comes to closing elements, so Angular's parser has
rules that specify which elements are implicitly closed when closing a tag.
The parser keeps track of the nesting of tag names using a stack and parsing
a closing tag will pop as many elements off the stack as possible, provided
that the elements can be implicitly closed.
For example, consider the following templates:
- `<div><br></div>`, the `<br>` is implicitly closed when parsing `</div>`,
because `<br>` is a void element.
- `<div><p></div>`, the `<p>` is implicitly closed when parsing `</div>`,
as `<p>` is allowed to be closed by the closing of its parent element.
- `<ul><li>A <li>B</ul>`, the first `<li>` is implicitly closed when parsing
the second `<li>`, whereas the second `<li>` would be implicitly closed when
parsing the `</ul>`.
In all the cases above the parsed structure would be correct, however the source
span of the closing `</div>` would incorrectly be assigned to the element that
is implicitly closed. The problem was that closing an element would associate
the source span with the element at the top of the stack, however this may not
be the element that is actually being closed if some elements would be
implicitly closed.
This commit fixes the issue by assigning the end source span with the element
on the stack that is actually being closed. Any implicitly closed elements that
are popped off the stack will not be assigned an end source span, as the
implicit closing implies that no ending element is present.
Note that there is a difference between self-closed elements such as `<input/>`
and implicitly closed elements such as `<input>`. The former does have an end
source span (identical to its start source span) whereas the latter does not.

We currently use 16 bits to store information about nodes in a view.
The 16 bits give us 65536 entries in the array, but the problem is that while
the number is large, it can be reached by ~4300 directive instances with host
bindings which could realistically happen is a very large view, as seen in #37876.
Once we hit the limit, we end up overflowing which eventually leads to a runtime error.
These changes bump to using 20 bits which gives us around 1048576 entries in
the array or 16 times more than the current amount which could still technically
be reached, but is much less likely and the user may start hitting browser limitations
by that point.
I picked the 20 bit number since it gives us enough buffer over the 16 bit one,
while not being as massive as a 24 bit or 32 bit.
I've also added a dev mode assertion so it's easier to track down if it happens
again in the future.

We recently reworked our `ng_rollup_bundle` rule to no longer output
ESM5 and to optimize applications properly (previously applications were
not optimized properly due to incorrect build optimizer setup).
This change meant that a lot of symbols have been removed from the
golden correctly. See: fd65958b88
Unfortunately though, a few symbols have been accidentally removed
because they are now part of the bundle as ES2015 classes which the
symbol extractor does not pick up. This commit fixes the symbol
extractor to capture ES2015 classes. We also update the golden to
reflect this change.

Previously, the i18n message extractor just quietly ignored messages that
it extracted that had the same id. It can be helpful to identify these
to track down messages that have the same id but different message text.
Now the messages are checked for duplicate ids with different message text.
Any that are found can be reported based on the new `--duplicateMessageHandling`
command line option (or `duplicateMessageHandling` API options property).
* "ignore" - no action is taken
* "warning" - a diagnostic warning is written to the logger
* "error" - the extractor throws an error and exits

`ls_rollup_bundle` is no longer needed since we could invoke `ng_rollup_bundle`
directly.
Background: language service runs rollup to produce a single file to reduce
startup time in the editor. However, due to the need to load dynamic versions
of typescript at runtime (think the case where users can change typescript
version in their editor), we hack the "banner" to export a CommonJS default function,
so that we could dynamically load the typescript module provided at runtime via AMD
and use it throughout the implementation.

Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.
- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
codebase as it is no longer tree shakable.
Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)
- [ ] Remove `ɵɵNgOnChangesFeature` from compiler. (It will no longer
be a feature.)
- [ ] Discuss the future of `Features` as they hinder meta-programing.

Fixes the following issues related to how we validate properties during JIT:
- The invalid property warning was printing `null` as the node name
for `ng-content`. The problem is that when generating a template from
`ng-content` we weren't capturing the node name.
- We weren't running property validation on `ng-container` at all.
This used to be supported on ViewEngine and seems like an oversight.
In the process of making these changes, I found and cleaned up a
few places where we were passing in `LView` unnecessarily.
