  ES31: Implement Geometry Shader inputs and outputs
  
  This patch intends to implement Geometry Shader inputs and
  outputs in ANGLE GLSL compiler.
  
  1. Only accept arrays as the inputs of a Geometry Shader.
  2. Allow unsized arrays as the inputs of a Geometry Shader after a
     valid input primitive declaration and assign size to them.
  3. Implement Geometry Shader outputs.
  4. Allow Geometry Shader inputs and outputs using interpolation
     qualifiers ('flat', 'smooth', 'centroid').
  5. Allow using 'location' layout qualifier on Geometry Shader inputs
     and outputs.
