  Move client attribs mask to front-end.
  
  The Vulkan and GL back-ends both had a client attributes mask.
  This consolidates them into the front-end, where it can also
  be used in the validation layer.
  
  Also includes a fix which was incorrectly setting the enabled
  mask in setVertexAttribFormatImpl.
