[dawn][native] Simplifies DeviceGuard with DeviceMutex.

- Moves the defer object to be a part of the DeviceMutex instead of
  the Device. This allows for simplifying cases where the device
  might be destroyed since the Defer now lives with the DeviceMutex
  on the additional Ref that it holds.
- This change also moves the code in Mutex around a bit so that the
  calls to Lock and Unlock are the ones responsible for updating
  state used for ASSERT checks. This is necessary to later expose
  private Lock/Unlock helpers in the Device class to implement
  unlocking before calling WaitFor* functions.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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, 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.
