ES31: Implement GL_OES_geometry_shader built-ins in GLSL compiler

This patch intends to implement all built-in constants, variables and functions defined in OpenGL ES 3.1 extension GL_OES_geometry_shader in ANGLE GLSL compiler. 1. Add all built-in constants defined in GL_OES_geometry_shader. 2. Add built-in functions EmitVertex() and EndPrimitive() required in Geometry Shader. 3. Add built-in variables gl_PrimitiveIDIn and gl_InvocationID to Geometry Shader. 4. Add built-in variables gl_PrimitiveID and gl_Layer to both Geometry Shader and Fragment Shader when GL_OES_geometry_shader is enabled.
