8bc31a515f feat(core): Allow other expression for exhaustive typechecking
When the switched expression is nested within a union, exhaustive typechecking needs to know which expression to check.
This change adds the possibility of specifying the expression to check:

```
@Component({
  selector: 'app-root',
  imports: [],
  template: `
    @switch (state.mode) {
      @case ('show') { {{ state.menu }}; }
      @case ('hide') {}
      @default never(state);
    }
  `,
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class App {
  state!: { mode: 'hide' } | { mode: 'show'; menu: number };;
}
```

64db486edc build: add rules for generating block/element API data (#52480)
Adds build rules for "artificially" generating `DocEntry` collections for block and element APIs. The two rules are very similar, but _just_ different enough that it's worth having two separate implementations.
