Jiawei Shao e89b48768b Validate texture usage scope with storage textures in one render pass 
This patch adds the validation rules on the texture usage scope with
storage textures in one render pass.
1. Write-only storage cannot be used in combination with anything else
in the same render pass.
2. Sampled and read-only storage are allowed to be used in the same
render pass.

This patch also adds dawn_unittests to test the storage texture usage
scope in one render pass:
1. read-only or write-only storage only
2. read-only or write-only storage + sampled
3. read-only or write-only storage + output attachment
4. read-only + write-only

This patch also removes kWritableBufferUsages as it is not used in Dawn
at all.

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
