libavcodec/qsvenc_hevc: encode RGB format rawvideo

Add support for hevc_qsv to input RGB format frame. It will
transform frame to yuv inside MediaSDK instead of using auto
scale. Now hevc_qsv supports directly encoding BGRA and X2RGB10
format. The X2RGB10 correspond to the A2RGB20 format and BGRA
correspond to RGB4 format in MediaSDK.
