  GL: Add emulateClipOrigin workaround
  
  Older Adreno drivers apply GL_CLIP_ORIGIN_EXT
  to the framebuffer instead of the clip space,
  thus causing various side-effects.
  
  Used a uniform to emulate the correct behavior.
  
  Drive-by:
  * Fixed a typo in ClipControlTest.OriginFrontFacing
  
  Fixed: angleproject:8392
