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.
