xwayland: Replace xwl_window::present_window with ::present_flipped
There's no need to keep track of the window which last performed a Present flip. This fixes crashes due to the assertion in xwl_present_flips_stop failing. Fixes issue #10. The damage generated by a flip only needs to be ignored once, then xwl_window::present_flipped can be cleared. This may fix freezing in the (hypothetical) scenario where Present flips are performed on a window, followed by other drawing requests using the window as the destination, but nothing triggering xwl_present_flips_stop. The damage from the latter drawing requests would continue being ignored.
