Erik Språng f0276c5d0f Lazy conversion to i420 buffer in SimulcastEncoderAdapter
This CL makes native the preferred buffer type, and if any of the
encoders in the adapter do not support native, the input frame will
be converted to I420 and used as input to encoders that require it,
along with any needed downscaling.
