Make that implizit with attaching/detaching controlsources. This is a lot easier
and has less invalid state (controlled property without control source).
This make the controller even more lightweight (no extra object, no extra lock,
less indirections). For object that don't use the controller the only 'overhead'
is a 3 unused fields in the gst_object structure.

API: Refactor GstController into the core controller which can take
a GstControlSource for providing actual values for timestamps.
Implement a interpolation control source and use this for backward
compatibility, deprecate a bunch of functions that are now handled
by GstControlSource or GstInterpolationControlSource.
Make it possible to disable the controller completely or only for
specific properties. Fixes#450711.
