Add additional buffer usage for indirect usage transition at backends

This patch adds an additional buffer usage for indirect usage transition
at the backends (Vulkan, D3D12) so that when recording the commands in
the command encoder at the front end we can avoid setting this internal
buffer usage in the usage tracker to signal that this buffer won't be
used as an indirect buffer because it needs to be used as a storage
buffer in a compute pass for validation or other purposes instead.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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, 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.
