D3D12: Add test for the crash issue about T2T copy with Depth32Float

Currently on D3D12 backend a device lost will occur when we do a T2T
copy under the following situations:
1. with Depth32Float
2. only copy one row
3. bufferCopyOffset == 256

This is because in current implementation it is possible for us to do
a copy with D3D12_SUBRESOURCE_FOOTPRINT.Depth > 1, which is not allowed
with DXGI_FORMAT_D32_FLOAT because this format is not supported to be
used as 3D textures.

This patch adds a regression test for this bug and we will fix it
later.

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
