avcodec/d3d12va_encode: texture array support for HEVC

Browse Source 
This patch adds support for the texture array feature
used by AMD boards in the D3D12 HEVC encoder.
In texture array mode, a single texture array is shared for all
reference and reconstructed pictures using different subresources.
The implementation ensures compatibility
and has been successfully tested on AMD, Intel, and NVIDIA GPUs.
