Previously, non-bracketed inputs (e.g. `xyz="foo"`) on downgraded components were initialized using `attrs.$observe()` (which uses `$evalAsync()` under the hood), while bracketed inputs (e.g. `[xyz]="'foo'"`) were initialized using `$watch()`. If the downgraded component was created during a `$digest` (e.g. by an `ng-if` watcher), the non-bracketed inputs were not initialized in time for the initial call to `ngOnChanges()` and `ngOnInit()`. This commit fixes it by using `$watch()` to initialize all inputs. `$observe()` is still used for subsequent updates on non-bracketed inputs, because it is more performant. Fixes #16212
