This CL complete the validation rules for CopyTextureForBrowser by:
 - Restrict source texture must have |CopySrc| and |Sampled| usage.
 - Restrict destinaton texture must have |CopyDst| and
   |RenderAttachment| usage.
 - Restrict sample counts of source texture and destination texture
   must be 1.
 - Restrict source copy origin.z must be 0.
 - Restrict CopyTextureForBrowser() can only copy to single slice.

A validation unittest is added to check.
