Reland "[wgpu-headers] Align device lost callbacks with webgpu.h and futures."

Relanding after the following fixes to users:
- Chrome: https://chromium-review.googlesource.com/c/chromium/src/+/5441439
- Skia/Graphite: https://skia-review.googlesource.com/c/skia/+/838480

Original change's description:
> [wgpu-headers] Align device lost callbacks with webgpu.h and futures.
>
> - Overrides wire::ObjectBase::Release logic for Device. This was
>   necessary because the DeviceLostEvent holds a ref to the Device.
> - Introduces non-progressing SystemEvents. This is needed because we
>   want to make sure that polling doesn't happen as long as a device
>   lost event exists.

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.
