video: make vdpau hardware decoding not use slices code path
For some reason, libavcodec abuses the slices rendering code path for
hardware decoding: in that case, the only purpose of the draw callback
is to pass a vdpau video surface object to video output. (It is unclear
to me why this had to use the slices code, instead of just returning an
AVFrame with the required vdpau state.)
Make this code separate within mpv, so that the internal slices code
path is not used for hardware decoding. Pass the vdpau state with
VOCTRL_HWDEC_DECODER_RENDER instead.
Remove the mencoder specific VOCTRLs.
