It is preparation step for step-into-worker. There are few changes:
- added breakOnAsyncCall flag for Debugger.stepInto. When flag is set
and async task is scheduled before step-into finished, we pause
execution with additional Debugger.paused event. This event contains
additional scheduledAsyncTaskId field.
- added Debugger.pauseOnAsyncTask. This method will pause execution as
soon as given async task is started.
This mechanism is replacement for Debugger.scheduleStepIntoAsync which
can not be used between multiple targets.
As result we can split async task scheduling in one target and
requesting break for this async task running in another target.
