D3D12: derive T2T workaround from TextureCopyBetweenDimensionsSupported 

Query D3D12_FEATURE_DATA_D3D12_OPTIONS13 to determine whether the device
supports copies between textures of different dimensions. If it does
not, or if D3D12_FEATURE_D3D12_OPTIONS13 is not supported, force enable
toggle
D3D12UseTempBufferInTextureToTextureCopyBetweenDifferentDimensions.
