T2T copies for depth-stencil formats where done one by one. Because the two per-aspect copies where submitted with no barriers in between them, incorrect synchronization could occur, making the end state of the destination texture incorrect. Fix this by using the combined aspects of the texture to perform copies, such that depth stencil are copied in a single command instead of two commands. Unfortunately the VVLs don't catch this issue, but the reporter of the issue confirmed that this commit fix the dawn_end2end_tests failures they were seeing.

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, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
