Currently when someone serves the "person_management" playground
example, there will be runtime exceptions by `@angular/forms` if
someone clicks on one of the two buttons rendered in the example.
This happens because the example is outdated and the input elements
using `ngModel` do not specify a proper "name" while being inside of
a `<form>` element. A name is required inside of a form. The failure
is not specific to Ivy and is not covered by any test because the e2e
tests for this example are just asserting that the page properly loads
(the error only shows up one of the buttons has been clicked)
This is the reason why these errors were never visibile to the e2e tests.
Though in order to make this example work, we should this fix these failures
so that the example can work as expected.
```
FullNameComponent.html:7 ERROR Error: If ngModel is used within a form tag, either the name attribute must be set or the form
control must be defined as 'standalone' in ngModelOptions.

Currently all playground examples are built with `tsc`
and served with the `gulp serve` task. In order to be able
to test these examples easily with Ivy, we now build and
serve the examples using Bazel. This allows us to expand our
Ivy test coverage and additionally it allows us to move forward
with the overall Bazel migration. Building & serving individual
examples is now very easy and doesn't involve building everything
inside of `/modules`.

Currently we depend on the "rules_webtesting" version that is
installed by "rules_typescript//:package.bzl". This version of
the webtesting rules comes with a very old version of Chromium
and the `chromedriver` that does not support capturing console
errors properly (with stack traces). Since we have a few e2e
tests that depend on console output (e.g. playground/src/source-map),
we need to make sure that these tests can pass upon Bazel
migration.

Changes `gulp format` to format only changed lines by default
(`gulp format:changed`) and introduces a new task, `gulp format:all` to
format all source files. Since formatting only changed lines should be
the more common action, it makes more sense as the shorter default.

Fixes Ivy not passing thrown errors along to the `ErrorHandler`.
**Note:** the failing test had to be reworked a little bit, because it has some assertions that depend on an error context being logged, however Ivy doesn't keep track of the error context.
This PR resolves FW-840.

Currently whenever someone creates a pull request, the NPM dependencies
are downloaded and installed. This is problematic because we have a lot
NPM dependencies with potentially large files that would need to be
downloaded (e.g. the Bazel binaries).
The caches are currently not being restored because we added the
`{Branch}` variable to the CircleCI cache key. Since every PR has a different
branch name (e.g. `devversion/refs/heads/my-banch`), the cache keys would
never match an existing cache key, and the PR would start fresh by
downloading everything.
We can safely remove the `{Branch}` variable from the cache key because
it does not provide any value since the cached files are based on the state
of the `yarn.lock` file and not based on the current branch name. This reduces
our dependency on the slow and sometimes **flaky** Yarn registry. We should
try to depend as few as possible on external services (e.g. see how Saucelabs
flakiness can cause trouble for the caretaker; same applies to flaky Yarn installs)

By default, `webdriver-manager update` will download the latest
ChromeDriver version, which might not be compatible with the Chrome
version included in the [docker image used on CI], causing CI failures.
Previously, we used to pin the ChromeDriver version on CI in
[ngcontainer's Dockerfile][2]. This was accidentally broken in #26691,
while moving from ngcontainer to default CircleCI docker images.
This commit fixes the issue by pinning ChromeDriver to a known
compatible version.

In Ivy, we support a new manual mode that allows for stricter control
over change detection in OnPush components. Specifically, in this mode,
events do not automatically mark OnPush views as dirty. Only changed
inputs and manual calls to `markDirty()` actually mark a view dirty.
However, this mode cannot be the default for OnPush components if we
want to be backwards compatible with View Engine. This commit re-adds
the legacy logic for OnPush components where events always mark views
dirty and makes it the default behavior.
Note: It is still TODO to add a public API for manual change detection.

Due to the fact that the test in 'ng_module_integration_spec.ts' relied on internal VE data structures (the '_def' field) to verify the state and the structure has changed in Ivy, this commit adds an Ivy version of the same test.

This commit fixes a bug in the Bazel builder in which the path to Bazel
executable is constructed using the project path. For non-default
project, the node_modules directory is actually one level above the
project path.
This PR fixes the bug by resolving node_modules with require.resolve().
It requires @bazel/bazel v0.22.1 because previous versions do not have
index.js or main field in package.json and would cause node module
resolution to fail.
This has been tested with both bazel and ibazel.

In 7cb8396, we improved the symbol test to remove suffixes from
the output, so "CIRCULAR$1" became "CIRCULAR". However, the logic
that checked for extra symbols depended on each symbol being unique.
If multiple symbols with the same name were added (e.g. pulled in
from separate files), they would be added to the map as "extras",
even if they were marked as expected in the golden file.
This commit updates the symbol checking logic to take multiple
symbols with the same name into account.

Previously, attempting to destroy a view with listeners more than once
throws an error during event listener cleanup. This happens because
`cleanup` field on the `TView` has already been cleared out by the time
the second destruction runs.
The `destroyed` flag on LView was previously being set in the `destroyLView` function,
but this flag was never _checked_ anywhere in the codebase. This commit
moves _setting_ this flag to the `cleanupView` function, just before
destroy hooks are called. This is necessary because the destroy hooks
can contain arbitrary user code, such as (surprise!) attempting to
destroy the view (again). We also add a check to `destroyLView` to skip
already-destroyed views. This prevents the cleanup code path from running twice.

With the release of @angular/bazel v7.2.3, the npm install step right
after `ng new` installs this version. However there is a bug in the
builder which results in bazel executable not found.
This bug was not discovered before because the dependencies of the
project created by `ng new` are not pinned.
The fix is to pin the version of @angular/bazel to 7.2.2 which relies on
global installation of bazel.

PR Close#28435
In View Engine, we supported @Input and @ContentChild annotations
on the same property. This feature was somewhat brittle because
it would only work for static queries, so it would break if a
content child was passed in wrapped in an *ngIf. Due to the
inconsistent behavior and low usage both internally and externally,
we will likely be deprecating it in the next version, and it does
not make sense to perpetuate it in Ivy.
This commit ensures that we now throw in Ivy if we encounter the
two annotations on the same property.

This commit updates the token used in fakeAsync test to the one available in both VE and R3 TestBeds. The goal of the test is to verify that fakeAsync works with inject function, so the actual token that is used for a test is irrelevant in that case. The logic to retrieve tokens from compiler injector (that the comment in "fixmeIvy" refers to) was implemented in PR #28196.

Prior to this change, generation of host bindings and host styles was guarded by the "if" statement, which always returned true. Enforcing more strict check for bindings length broke some tests, since host styling instructions generation were inside the same "if" block. This update decouples bindings instruction generation from styling instructions, which makes it less error prone.
PR Close#28379
Prior to this change we may encounter some errors (like pipes being used where they should not be used) while compiling Host Bindings and Listeners. With this update we move validation logic to the analyze phase and throw an error if something is wrong. This also aligns error messages between Ivy and VE.

The TypeTranslatorVisitor visitor returned strings because before it wasn't possible to transform declaration files directly through the TypeScript custom transformer API.
Now that's possible though, so it should return nodes instead.

The current DtsFileTransformer works by intercepting file writes and editing the source string directly.
This PR refactors it as a afterDeclaration transform in order to fit better in the TypeScript API.
This is part of a greater effort of converting ngtsc to be usable as a TS transform plugin.
