nvdec: Add support for 10bits 4:2:0 decoding

Browse source 
This commit includes h265 main-10 profile support if the device can
decode it.

Note that since h264 10bits decoding is not supported by nvidia GPU for now,
the additional code path for h264 high-10 profile is a preparation for
the future Nvidia's enhancement.
