dawn_wire: use memcpy on structures when possible

This patch sets 'is_wire_transparent' on the structures whose members
are all wire transparent and are not pointers, so that we can use
memcpy when serializing and deserializing these structures:
- GPUBlendComponent
- GPUColor
- GPUExtent3D
- GPULimits
- GPUOrigin3D
- GPUStencilFaceState
- GPUVertexAttribute
- GPUBlendState

In the next patch we will support memcpy on the qualified structures
whose members contain pointers (e.g. GPUVertexBufferLayout).

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
