Frontbuffer rendering will be dropped for modern platforms but before that we to prepare DRRS for it. intel_drrs_flush and intel_drrs_invalidate will not be called for platforms that will not support frontbuffer rendering so DRRS needs another way to be notified about to page flips so it can change between high and low refresh rates as needed.
