When we first started writing tests for Ivy, we did not yet have a
compatible compiler. For this reason, we set up the Ivy runtime tests
to run with generated code that we wrote by hand (instead of real code
generated by the compiler).
Now that we have a working Ivy compiler and TestBed infrastructure
that is compatible with Ivy, we should start writing integration
tests that leverage them (no more handwritten generated code!). This
will prevent bugs where the compiler code and runtime code become
out of sync (which is easy if they are tested separately). And
eventually, we should migrate all the existing runtime tests in
"core/test/render3" to TestBed and ngtsc.
To kick off this effort, this commit migrates some existing tests
from "core/test/render3/exports_spec.ts" and saves them in a new file
with the same name in the "core/test/acceptance" folder.

i18n instructions create text nodes dynamically and save them between bindings and the expando block in `LView`. e.g., they try to create the following order in `LView`.
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando (dirs, injectors) -- |
```
Each time a new text node is created, it is pushed to the end of the array and the `expandoStartIndex` marker is incremented, so the section begins slightly later. This happens in `allocExpando`.
This is fine if no directives have been created yet. The end of the array will be in the "dynamic text node" section.
| -- elements -- | -- bindings -- | -- dynamic i18n text -- |
However, this approach doesn't work if dynamic text nodes are created after directives are matched (for example when the directive uses host bindings). In that case, there are already directives and injectors saved in the "expando" section. So pushing to the end of `LView` actually pushes after the expando section. What we get is this:
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando -- | -- dynamic i18n text-- |
```
In this case, the `expandoStartIndex` shouldn't be incremented because we are not inserting anything before the expando section (it's now after the expando section). But because it is incremented in the code right now, it's now pointing to an index in the middle of the expando section.
This PR fixes that so that we only increment the `expandoStartIndex` if nothing was pushed into the expando section.

Prior to this change there was no i18n id sanitization before we output goog.getMsg calls. Due to the fact that message ids are used as a part of const names, some characters were bcausing issues while executing generated code. This commit adds sanitization to i18n ids used to generate i18n-related consts.

Currently, DOM node removal called `removeChild` on the saved parent
node when destroying a component. However, this will fail if the
component has been manually moved in the DOM. This change makes the
removal always use the node's real `parentNode` and ignore the provided
`parent`.

Ivy allows Components to extend Directives (but not the other way around) and as a result we may have Component and Directive annotations present at the same time. The logic that resolves annotations to pick the necessary one didn't take this into account and as a result Components were recognized as Directives (and vice versa) in case of inheritance. This change updates the resolution logic by picking known annotation that is the nearest one (in inheritance tree) and compares it with expected type. That should help avoid mis-classification of Components/Directives during resolution.

The logic to create additional files needed for Bazel are currently
hosted in `ng new`. Such files include the main.*.ts files needed
for AOT and a different angular.json to use Bazel builder, among others.
This commit refactors the logic into `ng add` so that it can be used to
perform the same modifications in an existing project. Users could do so
by running `ng add @angular/bazel`.
With this change, `ng new` effectively becomes an orchestrator that runs
the original `ng new` followed by `ng add @angular/bazel`.

Currently the "ngtsc` testing helpers resolve the `fake_core` NPM
package using the `TEST_SRCDIR` variable. This is problematic on Windows
where Bazel runfiles are not symlinked into the runfiles directory.
In order to properly resolve the NPM Bazel tree artifact, we use the
`resolveTreeNpmArtifact` runfile helper that properly resolves the artifact
properly on all platforms.

In order to support running "compiler-cli" tests that use the "test_support.ts"
utilities on Windows with Bazel, we need to imporve the logic that resolves NPM
packages and symlinks them into a temporary directory.
A more Bazel idiomatic and windows compatible way of resolving Bazel runfiles
is to use the "RUNFILES_MANIFEST" if present. This ensures that the NPM
packages can be also symlinked on Windows, and tests can execute properly
on Windows. Read more about why this is needed here:

Since we recently removed the `test.sh` script, and now run
all tests with Bazel, we can remove the unused logic that makes
compiler-cli tests pass in non-Bazel.
This cleans up the tests, and also makes it easier to write tests
without worrying about two ways of the Angular package output
(Bazel `ng_package` rules vs. old `build.sh` logic of building)

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.

Fixes Ivy not passing thrown errors along to the `ErrorHandler`.

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.

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.

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.

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.

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.

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.
