Corentin Wallez 36cd17488a dawn_wire: Correctly handle buffer state changes on Destroy() 
The server didn't take intercept the destroy() call which meant the
buffer could be unmapped by dawn_native without the status updated in
ServerBuffer. This caused crash when a subsequent UpdateMappedData
command was handled and tried to write into the mapped buffer.

The client needs to also track destroy() otherwise it could sent an
UpdateMappedData to a destroyed buffer which is a fatal error.

Tests are added that cover the client-server interaction for this, but
the pattern that the following is unfortunately not tested directly
against the wire server:

 - CreateBufferMapped
 - Destroy
 - UpdateMappedData

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
