  Migrate use of SuspendableTimer to EventLoop

Reviewed by Wenson Hsieh.

This PR introduces two new member functions scheduleTask and cancelScheduledTask to
EventLoop and EventLoopTaskGroup to replace the use of SuspendableTimer.

scheduleTask internally creates a new SuspendableTimer and returns the pointer value of
the timer as uintptr_t. This value can then be used to call cancelScheduledTask.

This PR replaces most uses of SuspendableTimer with scheduleTask and cancelScheduledTask.
