msdkh265enc: support 8-bit 422 encoding

Browse source 
The media driver can support HEVC 8-bit 422 encoding for non-lowpower
mode since ICL[1], so VPP is not needed for this case.

Sample pipeline:
gst-launch-1.0 videotestsrc ! video/x-raw,format=YUY2 ! msdkh265enc ! \
filesink location=output.h265
