This adds cogl_onscreen_template_set_swap_throttled() api that allows developers to specify their preference for swap buffer throttling up-front as part of the onscreen template that is used to create a CoglDisplay when initializing Cogl. This is desirable because some platforms may not support configuring swap throttling on a per framebuffer basis and also since applications often want to apply the same policy to all onscreen framebuffers anyway.
