[Animation Worklet] Fix flaky worklet-animation-with-fill-mode.https.html

Use a more robust method for waiting on receiving local times on main
thread when test is running with threaded compositing.

Previously we would wait for one async frame and some more time to ensure
we have received the local times on main thread. This can be flaky.
Instead wait until local time is no longer null which means worklet has
produced at least one frame and that frame has been synced with main.

To this end WorkletAnimation now exposes its effect (similar to regular
animations) and we use that to access the effect's local time.
