This is a reland of 8e9fbbe7caa414f7006d0568d918561b5ca9a94f 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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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
