Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time. This commit updates the code to avoid the second check for AOT-compiled components by checking whether `schemas` information is present in a logic that executes the unknown element check.

With Angular CLI version 9 RC 3 we can run a single migration for a package using the name of the migration schematic.
We need to pass the schematic name as a value to the `migrate-only` option.
Ex:
```
ng update @angular/core --migrate-only migration-v9-undecorated-classes-with-di
```

Use angular_ivy_enabled to determine if Ivy is being used for the ivy_test_selector.ts symbols.
Additionally, remove the reflect_metadata genrules as we not longer have a "jit" compile option
so all possible invocations result in the same generated file. Instead we can just commit this
file.

Prior to this commit, there was a runtime check in i18n logic to make sure "other" case is always present in an ICU. That was not a requirement in View Engine, so ICUs that previously worked may produce errors. This commit removes that restriction and adds support for ICUs without "other" cases.

Move a view only if it would end up at a different place.
Otherwise we would do unnecessary processing like DOM manipulation, query notifications etc.

When inserting a `viewRef` it is possible to not provide
an `index`, which is regarded as appending to the end of
the container.
If the `viewRef` already exists in the container, then
this results in a move. But there was a fault in the logic
that computed where to insert the `viewRef` that did not
account for the fact that the `viewRef` was already in
the container, so the insertion `index` was outside the
bounds of the array.

Prior to this commit, all styles extracted from Component's template (defined using <style> tags) were ignored by JIT compiler, so only `styles` array values defined in @Component decorator were used. This change updates JIT compiler to take styles extracted from the template into account. It also ensures correct order where `styles` array values are applied first and template styles are applied second.

This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same
host node were executed based on the order the directives were
matched, rather than the order the directives were instantiated
(i.e. injection order).
This discrepancy can cause issues with forms, where it is common
to inject NgControl and try to extract its control property in
ngOnInit. As the NgControl directive is injected, it should be
instantiated before the control value accessor directive (and
thus its hooks should run first). This ensures that the NgControl
ngOnInit can set up the form control before the ngOnInit
for the control value accessor tries to access it.

The assertion that we have in the `directiveInject` instruction is too restrictive and we came across some pattern where it throws unnecessarily. This commit removes that assertion for now and more detailed investigation is needed to decide is we need to restrict the set of TNodeType again.
This commit also adds a test which triggered the TNodeType.View to come up in the `directiveInject` instruction, so it might be useful to avoid regressions during further refactoring.

NgModule compilation in JIT mode (that is also used in TestBed) caches module scopes on NgModule defs (using `transitiveCompileScopes` field). Module overrides (defined via TestBed.overrideModule) may invalidate this data by adding/removing items in `declarations` list. This commit forces TestBed to recalculate transitive scopes in case module overrides are present, so TestBed always gets the most up-to-date information.

This change enables "var(--my-var)" to pass through the style sanitizer.
After consulation with our security team, allowing these doesn't create

there related to binding have been addressed via other changes to the

NgModules in Ivy have a definition which contains various different bits
of metadata about the module. In particular, this metadata falls into two
categories:
* metadata required to use the module at runtime (for bootstrapping, etc)
in AOT-only applications.
* metadata required to depend on the module from a JIT-compiled app.
The latter metadata consists of the module's declarations, imports, and
exports. To support JIT usage, this metadata must be included in the
generated code, especially if that code is shipped to NPM. However, because
this metadata preserves the entire NgModule graph (references to all
directives and components in the app), it needs to be removed during
optimization for AOT-only builds.
Previously, this was done with a clever design:
1. The extra metadata was added by a function called `setNgModuleScope`.
A call to this function was generated after each NgModule.
2. This function call was marked as "pure" with a comment and used
`noSideEffects` internally, which causes optimizers to remove it.
The effect was that in dev mode or test mode (which use JIT), no optimizer
runs and the full NgModule metadata was available at runtime. But in
production (presumably AOT) builds, the optimizer runs and removes the JIT-
specific metadata.
However, there are cases where apps that want to use JIT in production, and
still make an optimized build. In this case, the JIT-specific metadata would
be erroneously removed. This commit solves that problem by adding an
`ngJitMode` global variable which guards all `setNgModuleScope` calls. An
optimizer can be configured to statically define this global to be `false`
for AOT-only builds, causing the extra metadata to be stripped.
A configuration for Terser used by the CLI is provided in `tooling.ts` which
sets `ngJitMode` to `false` when building AOT apps.

Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.
Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.
As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.

TNode.inputs are initialised during directives resolution now so we know early
if a node has directives with inputs or no. We don't need to use undefined value
as an indicator that inputs were not resolved yet.
PR Close#33798
Before this change a public name of a directive's input
was stored in 2 places:
- as a key of an object on TNode.index;
- as a value of PropertyAliasValue at the index 1
This PR changes the data structure so the public name is stored
only once as a key on TNode.index. This saves one array entry
for each and every directive input.

Adds support for chaining of `styleProp`, `classProp` and `stylePropInterpolateX` instructions whenever possible which should help generate less code. Note that one complication here is for `stylePropInterpolateX` instructions where we have to break into multiple chains if there are other styling instructions inbetween the interpolations which helps maintain the execution order.

This refactorings clearly separates the first and subsequent creation execution
of the `template` instruction. This approach has the following benefits:
- it is clear what happens during the first vs. subsequent executions;
- we can avoid several memory reads and checks after the first creation pass
(there is measurable performance improvement on various benchmarks);
- the template instructions becomes smaller and should become a candidate
for optimisations / inlining faster;

When asking for a ViewContainerRef on <ng-container> we do reuse <ng-container> comment
node as a LContainer's anachor. Before this fix the act of re-using a <ng-container>'s
comment node would result in this comment node being re-appended to the DOM in the wrong
place. With the fix in this PR we make sure that re-using <ng-container>'s comment node
doesn't result in unwanted DOM manipulation (ng-gontainer's comment node is already part
of the DOM and doesn't have to be re-created / re-appended).

In View Engine, providers which neither used `useValue`, `useClass`,
`useFactory` or `useExisting`, were interpreted differently.
e.g.
```
{provide: X} -> {provide: X, useValue: undefined}, // this is how it works in View Engine
{provide: X} -> {provide: X, useClass: X}, // this is how it works in Ivy
```
The missing-injectable migration should migrate such providers to the
explicit `useValue` provider. This ensures that there is no unexpected
behavioral change when updating to v9.
