Chromium tracks the devices which live on the wire so it can automatically call tick on devices that have pending work. This used to be done by querying an (id, generation) pair and checking if it resolves to a non-null device. This CL adds a new way to query directly using the device, since a refactor in Chrome will change creation such that the id and generation is not known when a new device is requested. Also fixes a bug for device callbacks where the required callback userdata wasn't fully populated for devices created with requestAdapter. Update a test to check for this as well.

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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
