Use single FrameBufferController in VP8, created by a factory.

Browse Source 
This CL paves the way to making FrameBufferController injectable.

LibvpxVp8Encoder can manage multiple streams. Prior to this CL,
each stream had its own frame buffer controller, all of them held
in a vector by LibvpxVp8Encoder. This complicated the code and
produced some code duplication (cf. SetupTemporalLayers).

This CL:
1. Replaces CreateVp8TemporalLayers() by a factory. (Later CLs
   will make this factory injectable.)
2. Makes LibvpxVp8Encoder use a single controller. This single
   controller will, in the case of multiple streams, delegate
   its work to multiple controllers, but that fact is not visible
   to LibvpxVp8Encoder.

This CL also squashes CL #126046 (Send notifications of RTT and
PLR changes to Vp8FrameBufferController) into it.
