Implement 3D texture copy on D3D12: T2B and T2T

This change implements 3D texture copy on D3D12 for texture to
buffer and texture to texture copy for full copy upon the entire
3D texture.

It also uses a function named CopyBufferToTexture to wrap
CopyBufferTo3DTexture and CopyBufferTo2DTextureWithCopySplits.
Likewise, it uses another function named CopyTextureToBuffer to
wrap Copy3DTextureToBuffer and Copy2DTextureToBufferWithCopySplits.

BUG: dawn:547

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
