Replace EventLoopTimerPtr with EventLoopTimerHandle
https://bugs.webkit.org/show_bug.cgi?id=259955

Reviewed by Wenson Hsieh.

This PR replaces EventLoopTimerPtr, which is a type cast of EventLoopTimer*,
with a proper EventLoopTimerHandle which knows how to clean up itself at the end.

EventLoopTimerHandle is simply a wrapper around RefPtr<EventLoopTimer> now that
EventLoopTimer is reference counted.

This PR also removes cancelScheduledTask and cancelRepeatingTask from EventLoop
and EventLoopTaskGroup as the timer is automatically deleted when the handle dies.
