Fix internal storage buffer usage

TimestampQueryTests.ResolveTwiceToSameBuffer fails on Intel latest
driver on Windows, because the kInternalStorageBuffer is not treated
in buffer usage when adding resource barrier.

Add missed kInternalStorageBuffer in buffer usage and remove
D3D12_RESOURCE_STATE_UNORDERED_ACCESS from QueryResolve, which will be
added by kInternalStorageBuffer.

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
