Summary DisplayRefreshMonitorMac should hold a weak pointer to WebPage.

Instead of DisplayRefreshMonitorMac having a RefPtr to WebPage, it should have a weak pointer. Having a RefPtr could in theory create reference cycles. I have not seen any cases of this, but I think it would be better design to hold a weak pointer.
