... which were done after the promise has been resolved. Goal of this CL - change promise instrumentation to support better callbacks, chained after promise resolution and prepare instrumentation for adding new asyncTaskCreated instrumentation. Instrumentation changes: - asyncTaskScheduled(recurring) when promise is fulfilled or rejected, - asyncTaskCancelled when promise is collected (since [1] we can be sure that promise will survive scheduled microtasks). Minor changes: - async task type in inspector <-> debugger API transferred by enum instead of string, - Debug manages async task ids based on promise objects.
