Add renderer-agnostic delegate protocol.
The MTL renderer should also have a way to notify it's delegate
that it's content size changed.
The plan is to introduce this new protocol, move existing clients over
to implementing it in favour of RTCEAGLVideoViewDelegate, and then finally
removing the old protocol.
