Switches to tracking the registered directive nodes in the registry instead of a private static field. This allows us to reuse the logic in the handles.
Currently the `cdkDragHandle` directive registers itself with the parent by resolving it through DI. This doesn't work if the directive is declared in a separate embedded view (e.g. `ng-template`) that is then projected into the draggable element. It can be problematic when adding dragging support to a `mat-table`. These changes fix the issue by falling back to resolving the draggable directive through the DOM. Fixes angular#29475.
