  Revert "GL: Allow untranslated shaders to pass through on GLES"
  
  This reverts commit 4e77552b86a89b449ada6d6c18f84285f5812b1d.
  
  Reason for revert: breaks ChromeOS and fuzzers
  
  Bug: angleproject:398857482
  Original change's description:
  > GL: Allow untranslated shaders to pass through on GLES
  >
  > Add an EGL extension EGL_ANGLE_create_context_passthrough_shaders which
  > uses the NULL translator and passes the original shader to the driver.
  > The parser is still used for shader reflection.
