  Use packed enums on shader types in ANGLE renderer
  
  This patch uses a packed internal enum ShaderType everywhere we
  need a shader type instead of the GLenum value of the shader type.
  
  This patch also uses program::getAttachedShader(type) everywhere
  we need to get gl::Shader from a program in ANGLE.
