dawn_wire: Validate all objects are from the same device in the client

This is a temporary fix until dawn_wire can support multiple devices.
When using objects from different devices, the wire will inject an
error into the receiver object's device. Methods that return objects
will return a dummy object. Using the dummy object will cause a fatal
error on the server.

Without this fix, the server would blindly lookup an ObjectId which
could point to some other object. This would bypass same-device
validation and have incorrect results.

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
