Surface Vulkan validation messages in errors

This change ensures that when errors are raised from WebGPU, including
lost context errors, they can include any associated Vulkan validation
layer messages in the message text if backend validation is enabled.
This will allow these messages to be surfaced in places like when
running CTS tests on browser build infrastructure.

Because of how Vulkan messages are raised at the instance level, some
routing of the messages to the appropriate device needed to be added.
This is based on appending message IDs to object labels and then parsing
them out of the message when it comes in.

This change also makes Vulkan validation messages cause a device loss,
which is inline with the behavior of the D3D12 backend.

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
  • Tint is a compiler for the WebGPU Shader Language (WGSL).
