Wonkap Jang f3bb59209f avcodec/libvpxenc: add a way to explicitly set temporal layer id 
In order for rate control to correctly allocate bitrate to each temporal
layer, correct temporal layer id has to be set to each frame. This
commit provides the ability to set correct temporal layer id for each
frame.
