added 10 bit support for amf hevc.
before:

v2 - lost line returned in ff_amf_pix_fmts v3 - fixes after review v4 - extract duplicated code, fix incorrect processing of 10-bit input for h264

Can you explain what this CONVERTER_COLOR_PROFILE option is actually doing?
You've passed the primaries and transfer function to AMF options later on, but this seems to then only consider a subset of possible matrices rather than just passing that through as well to write into the VUI metadata. Why?
(If this isn't supported by AMF then a more correct solution might be to insert a metadata BSF to edit the correct values into the output stream after it has been encoded.)
When RGB surface is submitted, AMF encoder not only writes VUI header but also does color conversion. In this case CONVERTER_COLOR_PROFILE defines
color conversion matrix. This conversion may happen with shaders or inside VCN if it is capable to do so.
These are input parameters for conversion – if conversion is involved: AMF_VIDEO_ENCODER_INPUT_COLOR_PROFILE – for color conversion: limited number of color spaces is supported. AMF_VIDEO_ENCODER_INPUT_TRANSFER_CHARACTERISTIC AMF_VIDEO_ENCODER_INPUT_COLOR_PRIMARIES AMF_VIDEO_ENCODER_INPUT_HDR_METADATA These are output parameters for conversion and data for VUI: AMF_VIDEO_ENCODER_OUTPUT_COLOR_PROFILE – for VUI only, used if color conversion is done outside of AMF AMF_VIDEO_ENCODER_OUTPUT_TRANSFER_CHARACTERISTIC AMF_VIDEO_ENCODER_OUTPUT_COLOR_PRIMARIES AMF_VIDEO_ENCODER_OUTPUT_HDR_METADATA It would be possible to add unsupported color matrices via editing VUI in the output stream but it is better to do it via a separate patch as supported covers most common use cases.

Is this the input bit depth or the codec bit depth? (Can they be different?)
According to AMF documentation, this property "sets the number of bits in each pixel’s color component in the encoder’s compressed output bitstream". We should set up correct bit depth for encoder if we have 10-bit input
