For some main-10 stream, sometime the luma is 8 bits while chrome is more
than 8 bits, which cause using the wrong NV12 surface as the render target
and decoding error.
Fix#176
The old mapping values return by gst_vaapi_utils_h265_get_profile_idc is
wrong, though GST_H265_PROFILE_IDC_MAIN and GST_H265_PROFILE_IDC_MAIN_10
happened to be the correct value.
We only support Annex A profile_idc (1-4).
Add 444 10bit yuv format Y410, which can be used to decode
main-444 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.
Add 422 10bit yuv format Y210, which can be used to decode
main-10-422 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.

Only supporting vaapidecode ! vaapisink combination for now.
Missing dependencies:
1: No support for P010 video format in GStreamer
2: No support for P010 vaGetImage()/vaPutimage() in vaapi-intel-driver
3: As a result of 1&2 , we have no support for Vaapi Video memory mapping
through GstVideoMeta.
Right now we only set chroma format (YUV420 with more than 8 bits per channel)
for surface pool and keeping GST_VIDEO_FORMAT as ENCODED. The underlying format
of the surfaces is implementation (driver) defined, which is P010.
