Chuck Jazdzewski 82bcd83566 feat(compiler): allow ngIf to use the ngIf expression directly as a guard
Allows a directive to use the expression passed directly to a property
as a guard instead of filtering the type through a type expression.

This more accurately matches the intent of the ngIf usage of its template
enabling better type inference.

Moved NgIf to using this type of guard instead of a function guard.

Closes: #20967

Chuck Jazdzewski 634d33f5dd fix(compiler): support referencing enums in namespaces (#20947)

Chuck Jazdzewski 70cd124ede feat(compiler): add a pseudo $any() function to disable type checking (#20876)
`$any()` can now be used in a binding expression to disable type
checking for the rest of the expression. This similar to `as any` in
TypeScript and allows expression that work at runtime but do not
type-check.

Chuck Jazdzewski e7d9cb3e4c feat(compiler): narrow types of expressions used in *ngIf (#20702)
Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.

NgIf was modified to declare an input guard on ngIf.

After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.

For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.

The template compiler will generate code similar to,

```
  if (NgIf.ngIfTypeGuard(instance.person)) {
    instance.person.name
  }
```

to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

Vikram Subramanian fbc9537952 perf(compiler): fix perf issue in loading aot summaries in jit compiler
The current `flattenSummaries` function re-process the same NgModule
summary even if it has been processed before. Certain modules like
CommonModule are repeated multiple times in the module tree and it is
expanded out every time.

This was making unit tests using AOT summaries really slow. This will
also slow down JIT bootstrap applications that load AOT summaries for
component libraries.

The fix is to remember which summaries were seen before and not to
process them again.

Victor Berchet 0833b59aab refactor(core): add a checkIndex to the compiler view nodes
Each node now has two index: nodeIndex and checkIndex.

nodeIndex is the index in both the view definition and the view data.
checkIndex is the index in in the update function (update directives and update
renderer).

While nodeIndex and checkIndex have the same value for now, having both of them
will allow changing the structure of view definition after compilation (ie for
runtime translations).

  to all generated files

use `importAs` from flat modules when writing summaries
- i.e. prevents incorrect entries like @angular/common/common in the .ngsummary.json files.

change interaction between ng and ts to prevent race conditions
- before Angular would rely on TS to first read the file for which we generate files,
  and then the generated files. However, this can break easily when we reuse an old program.
