vpx: Allow odd width/height decoding

Allow the vpx (vp8 and vp9) decoder components to decode videos
with odd dimensions. This supported by the underlying software
decoders.

We create a graphic buffer that is width aligned to 16 and
height aligned to 2 and then set the "crop" value to the
appropriate video dimensions.
