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.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
