Elad Alon fb0878197e Reland "Refactor handling of configuration overrides from Vp8FrameBufferController"
This is a reland of 4d6795f828

Original change's description:
> Refactor handling of configuration overrides from Vp8FrameBufferController
>
> Make Vp8FrameBufferController::UpdateConfiguration return a set
> of desired overrides. These overrides are cumulative with
> previously returned override sets.
