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.

Fixes: #19756?

Tobias Bosch 0cc77b4a69 refactor(compiler): split compiler and core (#18683)
After this, neither @angular/compiler nor @angular/comnpiler-cli depend
on @angular/core.

This add a duplication of some interfaces and enums which is stored
in @angular/compiler/src/core.ts

BREAKING CHANGE:
- `@angular/platform-server` now additionally depends on
  `@angular/platform-browser-dynamic` as a peer dependency.

Tobias Bosch a80ac0a8d3 fix(core): make decorators closure safe (#16905)
This is required as e.g. `token` from `@Inject` is
accessed in string form via makeParamDecorator
but as a property in the `ReflectiveInjector`.

Closes #16889 as this is a more general fix.
