  ES31: Support EXT_geometry_shader in GLSL compiler
  
  This patch intends to support "EXT_geometry_shader" as a valid
  extension string in ANGLE GLSL compiler.
  
  We decide to support it because in dEQP-GLES31 all geometry
  shader related tests are using "EXT_geometry_shader" instead of
  "OES_geometry_shader".
  
  1. Support new extension string "EXT_geometry_shader"
  2. Enable geometry shader layout qualifiers with EXT_geometry_shader
  3. Enable geometry shader builtins with EXT_geometry_shader

  TEST=angle_unittests
