This CL adds two helpers for more ergonomic processing of ChainedStructs. 1. FindInChain(): Iterates through the chain and automatically casts the ChainedStruct into the appropriate child type before returning. 2. ValidateSTypes(): Verifies that the chain only contains structs with sTypes from a pre-defined set. This also allows the caller to specify one-of constraints. 3. ValidateSingleSType(): Verifies that the chain contains a single struct with a specific sType or is an empty chain. This is a common case of |ValidateSTypes()| and is separated out as a fast-path.

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
