Reland "[dawn][headers] Add GetLostFuture to native and wire."

This is a reland of commit c45ef7eb9c4a34299dcf284bab1367d8dcea8c42

- Changes fixes the leak seen in ASAN runs when trying to roll
  Dawn into Chromium. The leak was caused because the device lost
  callback wasn't running. To fix this in Chromium, we only
  needed to update the callback mode of the lost event in the wire
  server adapter to use AllowSpontaneous. However, to fix the
  issue fully in native also, we need to make sure that we drop
  the reference to the lost event in the device as soon as the
  last external reference to the device is dropped as well.

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.
