cairooverlay: Add property for drawing on a transparent surface and then blending
...
This allows us to use the GstVideoOverlayComposition API and correctly

At a later point we can attach the meta to the buffer instead of
blending ourselves if downstream supports that.

The other elements are not that interesting now that we're
using pangocairo in the pango plugin, and should probably
just be removed.
