[Request]: Add YUV 444 encoding/decoding for high quality video

[RGB-loop]

Nvidia Video Codec SDK and Intel MSDK support H265 444 encoding and decoding in latest release version. Besides, YUV444 encoding is quite important in design scenarios.

This needs to be supported by HW. AMF provides access to what is available. We started Wiki with HW information: https://github.com/GPUOpen-LibrariesAndSDKs/AMF/wiki/GPU%20and%20APU%20HW%20Features%20and%20Support

I don't see where that wiki page says anything about YUV 444, am i misreading it?
