Thibault Saunier 5e448921d8 ges: Move TimeOverlayClip out of GESTestClip
This was complexifying the implementation for very little gain.
Each source type should ideally have its own API.

In that patch we make it so we do not have to subclass anything
but instead use GESAsset to pass information about how the pipeline
should look like.
