  ES31: Add link validation on geometry shader itself
  
  This patch intends to support program link validation on geometry
  shader itself. A link error should occur when linking a program with
  a geometry shader that lacks input primitive or output primitive or
  the declaration of 'max_vertices'.
  
  This patch also adds the support of linking a program with geometry
  shader in angle_end2end_tests.
