Currently, debugger pauses on async call schedule and then waits for Debugger.pauseOnAsyncCall with parentStackTraceId to actually schedule the pause. This CL combines these two steps: - For local async tasks, it just stores m_taskWithScheduledBreak at the time of schedule, to be able to pause once this task is run. - For external async tasks, it plumbs "should_pause" boolean in V8StackTraceId from the point of schedule to the point of execution, and schedules a pause once externalAsyncTaskStarted is called with "should_pause" set to true. This approach greatly simplifies the implementation, and reduced frontend to a single "breakOnAsyncCall: true" parameter in Debugger.stepInto. Drive-by: introduce hasScheduledBreakOnNextFunctionCall() to make SetBreakOnNextFunctionCall management more robust. Note: artificial pauses at async call schedule time are gone from test expectations - we now only pause when user actually wants to pause, which makes protocol much simpler.
