Zhaoming Jiang 3d3e1757c4 Reland "Recording timing info in trace events when D3D12 queue submit" 
This is a reland of 8e9fbbe7ca

Add a toggle RecordDetailedTimingInTraceEvents. When this toggle is
enabled, record detailed timing information in trace events right
before calling ExecuteCommandLists on a D3D12 command queue, and the
information includes system time, CPU timestamp, GPU timestamp, and
their frequency. All Windows APIs used here are supported since Windows
2000.

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
