ES3.1: Implement framebuffer parameters api for opengl part.

Add new framebuffer parameters that can be set with glFramebufferParameteri
and queried with glGetFramebufferParameteriv.
GL_FRAMEBUFFER DEFAULT WIDTH
GL_FRAMEBUFFER_DEFAULT_HEIGHT
GL_FRAMEBUFFER_DEFAULT_SAMPLES
GL_FRAMEBUFFER_DEFAULT_FIXED_SAMPLE_LOCATIONS
