direct3d11: adapt DXGI_HDR_METADATA_HDR10 to VLC internal format
The VLC and libvlc format is the one from HEVC SEI which is ANSI/CTA 861-G.
The Microsoft format differs from this format in MaxMasteringLuminance where the
values is not in 1/10000th of a nit but in nit.
We also reorder the setting of values to match the order of the structure.
This is also the same order as libvlc.
