This CL refactor the logic adapter creating device toggles set when creating device and the way device holding its toggles. This CL also introduce the concept "toggle stage", currently "device stage" only but in future will add "instance stage" and "adapter stage" for instance and adapter toggles. No changes on Dawn API. More details: 1. Introduce `TogglesState` objects that represent the complete toggles state of a device (and will used for instance and adapter in future). 2. When creating a device, adapter set up a TogglesState object for it in `AdapterBase::CreateDeviceInternal` and `Adapter::SetupBackendDeviceToggles`, no other place would change the device's toggles state. This change simplify the logic. 3. Introduce the `ToggleStage` enum for every toggle and `TogglesState` object. Currently we only have `Device` toggle stage, but in future will have `Instance` and `Adapter` for instance and adapter toggles.

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, Metal, Vulkan and OpenGL. See per API support for more details.
- 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) that can be used in standalone to convert shaders from and to WGSL.
