Due to sanitization being stored as a temp/global value between
instructions, unit tests randomly failed because one test failed
to clean up its temporary value. This patch fixes this issue.
`i18nAttributes` instructions always occur after the element instruction. This means that we need to treat `i18n-` attributes differently.
By defining a specific `AttributeMarker` we can ensure that we won't trigger directive inputs with untranslated attribute values.

Changed runtime i18n to define attributes with bindings, or matching directive inputs/outputs as element properties as we are supposed to do in Angular.
This PR fixes the issue where directive inputs wouldn't be trigged.

Commit 0df719a46 introduced registration of NgModules with ids when compiled
with AOT, and f74373f2d corrected the timing to avoid issues with tree
shaking. Neither of these approaches were correct.
This commit fixes the timing to match View Engine and avoid tree shaking
issues, as well as fixes a bug with the registration of imported module ids.
A new Ivy-only test is added which verifies that modules get registered
correctly under real-world conditions.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This fixes a collision between #30639 and #30543 where the latter added
usages of @ViewChild without the static flag present, but the former
made the flag required.
PR Close#30666
This commit makes the static flag on @ViewChild and @ContentChild required.
BREAKING CHANGE:
In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.
@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.

This patch in the second runtime change which refactors how styling
bindings work in Angular. This patch refactors how map-based
`[style]` and `[class]` bindings work using a new algorithm which
is faster and less complex than the former one.
This patch is a follow-up to an earlier refactor which enabled
support for prop-based `[style.name]` and `[class.name]`
bindings (see f03475cac8).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

Depending on which placeholders the translation uses, there are some legitimate cases where we might not use all placeholder replacements in `i18nPostprocess`. For example if some of the placeholders of the original messages have been removed in the translation.

DEPRECATION:
Angular previously has supported an integration with the Web Tracing
Framework (WTF) for performance testing of Angular applications. This
integration has not been maintained and likely does not work for the
majority of Angular applications today. As a result, we are deprecating
the integration in Angular version 8.
This deprecation covers the following public APIs:
* `WtfScopeFn`
* `wtfCreateScope`
* `wtfStartTimeRange`
* `wtfEndTimeRange`
* `wtfLeave`

Currently if a project has source-files with syntax failures and the migration
has been started on a broken project, we silently migrate *as much as possible*,
but never notify the developer that the project was in a broken state and that
he can re-run the migration after the failures are fixed.
Additionally the template strategy does not need to exit gracefully if it detects
Angular semantic diagnostics on generated files (template type checking). These
diagnostics are not relevant for the query timing analysis.

We are removing the prompt for the `static-query` migration and make the
template strategy the migration strategy for the migration. The usage
strategy is good for best-practices, but for now we want to ensure that
the migration is a seamless as possible and that is only achievable my
re-using the same logic that View Engine uses for determining the
timing of a query.

Prior to this change a component was considered unresolved (i.e. having dynamic resources that should be loaded, like external template or stylesheets) even if template override was provided as an empty string (for example, via TestBed.overrideTemplateUsingTestingModule call). This commit fixes the condition that previously treated empty string as an absent template value.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

Prior to this change we processed binding expression (including bindings with pipes) in i18n attributes before we generate update instruction. As a result, slot offsets for pipeBind instructions were calculated incorrectly. Now we perform binding expression processing when we generate "update block" instructions, so offsets are calculated correctly.

Currently we try to parse CLI workspace configurations gracefully by
using the native `JSON.parse()` method. This means that the CLI workspace
configuration needs to follow the strict JSON specification because otherwise
the migrations would not be able to find TypeScript configurations in the CLI
project where JSON5 workspace configurations are supported.
In order to handle such workspace configurations, we leverage the JSON
parsing logicfrom the `@angular-devkit/core` which is also used by the CLI.

BREAKING CHANGE
In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character
