Tint automatically infers a storage class of `handle` for these types
of variable, as per the WGSL spec. Explicitly specifying a storage
class for them will soon become an error.

This CL updates the tests with WGSL sources to use // for comments

This CL enable CopyTextureForBrowser to accept options. The first
supported option is flipY, which can be implemented through scale and
offset uniforms.

In previous internal shader, we draw a just fit-in rectangle to do the
copy. But there is arithmetic precision issues in border pixels when
copy from a large texture.
ANGLE handle the same issue by drawing a large triangle. Dawn adopte the
same idea here

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.
