This commit adds a new compiler pipeline that isn't dependent on global
analysis, referred to as 'ngtsc'. This new compiler is accessed by
running ngc with "enableIvy" set to "ngtsc". It reuses the same initialization
logic but creates a new implementation of Program which does not perform the
global-level analysis that AngularCompilerProgram does. It will be the
foundation for the production Ivy compiler.

`ng.performCompilation` can return an `undefined` program, which is not handled by ngc-wrapped.
Avoid crashing by checking for the error return and returning the diagnostics.

The bug fixed here steams from the fact that we are traversing too far up
in the views tree hierarchy in the destroyViewTree function.
The logic in destroyViewTree is off if we start removal at an embedded view
without any child views. For such a case we should just clean up (cleanUpView)
this one view without paying attention to next / parent views.

A long time ago Angular used to support both those attribute notations:
- `*attr='binding'`
- `template=`attr: binding`
Because the last notation has been dropped we can refactor the binding parsing.
Source maps will benefit from that as no `attr:` prefix is added artificialy any
more.

In certain cases seen in production, simplify() can returned
undefined when simplifying decorator metadata. This has proven tricky
to reproduce in an isolated test, but the fix is simple and low-risk:
don't attempt to spread an undefined set of annotations in the first
place.

This patch is in response to #23401 where a non-const enum was being
compiled as an empty object when used in an animation player when
`ng build --prod` was being processed. This patch is a immediate fix
for the issue and #23400 tracks it.

Ivy definition looks something like this:
```
class MyService {
static ngInjectableDef = defineInjectable({
…
});
}
```
Here the argument to `defineInjectable` is well known public contract which needs
to be honored in backward compatible way between versions. The type of the
return value of `defineInjectable` on the other hand is private and can change
shape drastically between versions without effecting backwards compatibility of
libraries publish to NPM. To our users it is effectively an opaque token.
For this reson why declare the return value of `defineInjectable` as `never`.

- Remove default injection value from `inject` / `directiveInject` since
it is not possible to set using annotations.
- Module `Injector` is stored on `LView` instead of `LInjector` data
structure because it can change only at `LView` level. (More efficient)
- Add `ngInjectableDef` to `IterableDiffers` so that existing tests can
pass as well as enable `IterableDiffers` to be injectable without
`Injector`

This change changes:
- compiler uses `directiveInject` instead of `inject` for `Directive`s
- unifies the flags in `di` as well as `render3`
- changes the signature of `directiveInject` to match `inject` In prep for #23330
- compiler now generates flags for injection.

In [glob patterns][1], the `*` wildcard is supposed to match 0 or more
characters.
For reference:
- This is also how `*` works in other implementations, such as
`.gitignore` files or Firebase hosting config.
- Some popular JS implementations (e.g. [minimatch][2], [micromatch][3])
work differently, matching 1 or more character (but not 0).
This commit "fixes" the minimal glob support in
`@angular/service-worker` to allow `*` to also match 0 characters.

The ServiceWorker will redirect navigation requests that don't match any
`asset` or `data` group to the specified index file. The rules for a
request to be classified as a navigation request are as follows:
1. Its `mode` must be `navigation`.
2. It must accept a `text/html` response.
3. Its URL must match certain criteria (see below).
By default, a navigation request can have any URL except for:
1. URLs containing `__`.
2. URLs to files (i.e. containing a file extension in the last path
segment).
While these rules are fine in many cases, sometimes it is desirable to
configure different rules for the URLs of navigation requests (e.g.
ignore specific URLs and pass them through to the server).
This commit adds support for specifying an optional `navigationUrls`
list in `ngsw-config.json`, which contains URLs or simple globs
(currently only recognizing `!`, `*` and `**`).
Only requests whose URLs match any of the positive URLs/patterns and
none of the negative ones (i.e. URLs/patterns starting with `!`) will be
considered navigation requests (and handled accordingly by the SW).
(This is an alternative implementation to #23025.)

When compiling templates the compiler would often bind to
closest context rather than the component context.
The only time one should be binding to the cont component is
in explicit cases where the inner template declares local variable.
PR Close#23168
Given
```
<div *ngFor=”…” (click)=“doSomething()”>
```
Before `doSomething` would execute on the inner template context, which
is incorrect. The correct behavior is to execute on the top level context
of the component.

rxjs 6.0.0 breaks strictMetadataEmit as they now publish a .d.ts file with a
structure like:
declare export class Subscription {
static EMPTY: Subscription;
}
This generates metadata which contains an error, and fails the strictMetadataEmit
validation. There is nothing a library author can do in this situation except to
set strictMetadataEmit to false.
The spirit of strictMetadataEmit is to validate that the author's library doesn't
do anything that will break downstream users. This failure is a corner case which
causes more harm than good, so this commit disables validation for metadata
collected from .d.ts files.

Lowering expressions in flat module metadata is desirable, but it won't
work without some rearchitecting. Currently the flat module index source
is added to the Program and therefore must be determined before the rest
of the transforms run. Since the lowering transform changes the set of
exports needed in the index, this creates a catch-22 in the index
generation.
This commit causes the flat module index metadata to be generated using
only those transforms which are "safe" (don't modify the index).

As we no longer create native (RNode) comment nodes for containers,
we need to execute logic for finding a next sibiling node with RNode
when inserting a view.
The mentioned logic need to be updated for the case of dynamically
created containers (LContainerNode). Indeed, we need to be able to
descend into dynamically inserted views while looking for a RNode.
To achieve this we need to have a pointer from a host LNode to a
dynamically created LContainerNode).
