Summary:
The `requestIdleCallback` sometimes doesn't work in `Debug JS Remotely` mode if I use real device, the callback will never called. I guess it may be debugger worker and device caused by the time gap, or some cause websocket blocking, so it's just sometimes happening.
I think we can support [options](https://developer.mozilla.org/zh-TW/docs/Web/API/Window/requestIdleCallback#Parameters) for that.
Added an example `Run requestIdleCallback with timeout option` for Timers of UIExplorer, it use `{ timeout: 100 }` option with burn CPU 100ms, we can see `didTimeout` is true.

Summary:
These are bad since the app might not be foregrounded anymore and it also keeps the timing module awake. We could fix the latter but the former would require someone adding AlarmManager support.
Open to better/more helpful ideas for the warning message but there's not a ton we can tell them to do right now.

Summary:
**Motivation**
This PR fixes the flow type definition of StackFrame in parseErrorStack.js. The methodName was missing and the column could be `null`. We integrate with it in our codebase and we wanted to use `methodName`, but flow complained.
Refer to this file for possible values: [github.com/errwischt/stacktrace-parser/blob/master/lib/stacktrace-parser.js](https://github.com/errwischt/stacktrace-parser/blob/master/lib/stacktrace-parser.js)
This also allowed me to remove a flow error suppression.
**Test plan (required)**
I ran flow on the project, no errors
Closes https://github.com/facebook/react-native/pull/12499
