Add a helper function that ensures any queued virtual input events have been flushed from the input thread. This works by posting a task to the input thread, which will itself queue another callback back to the main thread. Once the main thread callback is invoked, the flush call is unblocked and the function returns. Upon this, any previously emitted virtual input event should have already passed through the input thread back into the main thread, however not necessarily fully processed. For making sure it has been processed, one also have to make sure the stage has been updated, e.g. via `meta_wait_for_paint()`. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2727>
