Add validations on the texture-to-texture copies within same texture
This patch adds validations on the texture-to-texture copies within the
same texture to align with the latest change in WebGPU SPEC: When the
source and destination textures are the same one, the source and the
destination subresources involved in the copy must not overlap.
Note that we don't enable the newly added end2end tests on D3D12
because when doing texture-to-texture copy within the same texture, we
need to set the source subresources into TRANSFER_SRC state and set the
destination subresources into TRANSFER_DEST state, while right now we
don't support subresource tracking on D3D12.
