[GLIB] Skip run loop observer notifications earlier for activities with no
observers registered
https://bugs.webkit.org/show_bug.cgi?id=302392
Reviewed by Nikolas Zimmermann.
We currently don't use Activity::AfterWaiting but on every run loop
iteration we iterate the observers again after waiting for sources to
check if there's any to notify. We could keep a count of observers
registered for every activity and early return from
RunLoop::notifyActivity when the given activity doesn't have observers
registered. This patch adds a new class OptionCountedSet with the
minimum API to help with this.
