[directxtex] port update for January 2023 release

[walbourn]

• Fixed memory overwrite bug in ConvertToSinglePlane that can lead to a potential security issue for untrusted planar video format DDS files
• Make sure ScratchImage zero-fills image memory
• Fix DirectX12 GPU-validation warnings for texture loaders

First issue is a fix for a security bug reported by a researcher. See this notice.
