src: do not call into JS in the maxAsyncCallStackDepthChanged interrupt

If Debugger.setAsyncCallStackDepth is sent during bootstrap,
we cannot immediately call into JS to enable the hooks, which could
interrupt the JS execution of bootstrap. So instead we save the
notification in the inspector agent if it's sent in the middle of
bootstrap, and process the notification later here.
