  WebGPU: Add extensions for importing external textures
  
  Add EGL_ANGLE_device_webgpu which exposes the adapter and device used
  by ANGLE internally.
  
  Add EGL_ANGLE_webgpu_texture_client_buffer which allows importing
  external WGPUTexture handles if they share the same device as ANGLE
  (queried from EGL_ANGLE_device_webgpu).
