    clutter: add tracing for frameclock cycle
    
    This adds a new frameclock tracing mark for a single cycle of the frame
    clock. Doing so allows Sysprof to potentially do more with the information
    that happens during the frameclock. For example, we can now find
    allocations that happen while the frame clock is advancing.
