Enable CopyTests_T2T/CopyWithinSameTexture* tests on D3D12

This patch enables the tests CopyTests_T2T/CopyWithinSameTexture* on
D3D12 after the D3D12 texture subresource tracking has been supported.

This patch also changes the related comment in Vulkan as WebGPU CG has
already decided to disallow the overlaps among source and destination
subresources in texture-to-texture copies.
