Add Pepper support for several GL extensions

Add support to the command buffer code generator to generate multiple pepper interfaces, and use that to generate interfaces for ANGLE_instanced_arrays, ANGLE_framebuffer_blit, ANGLE_framebuffer_multisample, CHROMIUM_enable_feature, and CHROMIUM_map_sub.
