* feat(common): support `as` syntax in template/* bindings Closes #15020 Showing the new and the equivalent old syntax. - `*ngIf="exp as var1”` => `*ngIf="exp; let var1 = ngIf”` - `*ngFor="var item of itemsStream |async as items”` => `*ngFor="var item of itemsStream |async; let items = ngForOf”` * feat(common): convert ngIf to use `*ngIf="exp as local“` syntax * feat(common): convert ngForOf to use `*ngFor=“let i of exp as local“` syntax * feat(common): expose NgForOfContext and NgIfContext
