Move the ActivityEmbedding Task visibility filter to the client

Before, we only send TaskFragment info event to the client side when the
Task is visible, which may result some TaskFragments stuck in an
intermediate state. Now, we also send the info event to the client if
the app owns any visible Task, and let the client organizer to determine
if it wants to update the TaskFragments.
