Like copyTextureCHROMIUM in Chromium, CopyImageBitmapToTexture can use internal pipeline to do the GPU uploading. But Dawn doesn't support internal pipeline now. This patch adds the first internal pipeline for Dawn and add the API CopyTextureForBrowser to use internal pipeline to do gpu uploading. The patch integrates very simple wgsl vertex/fragment shaders to do simple direct blit to verify the whole system works.

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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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
