Austin Eng 5397f9f9d0 Add basic or stub implementations of upstream instance/adapter APIs 
Adds upstream instance/adapter APIs. In dawn_native, the basic APIs
to get limits and properties are implemented, but requestAdapter and
requestDevice are not. In dawn_wire, nothing is implemented, but the
stub definitions are put in place, as well the mechanism to inject
WGPUInstance into the wire.

There is a lifetime concern with WGPUInstance and WGPUAdapter on the
wire in that we need to ensure that the client cannot free the
instance or adapter while they are in use. In the near term, this is
not a problem because Chromium will always hold ownership of the
instance and adapters outside of the wire - i.e. it won't inject and
then release ownership.

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
