Haihao Xiang c0e809d6b8 msdkh265enc: add support for screen content coding extension 
Because the valid input formats for screen content coding extension is
a subset of input formats for range extension, user must specify the
profile for screen content coding extension in the caps filter

Example:
gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12 ! msdkh265enc
low-power=1 ! video/x-h265,profile=screen-extended-main ! fakesink
