[TIMOB-25345] Windows: Prevent app from suspension

According to the studies from [TIMOB-25019](https://github.com/appcelerator/titanium_mobile_windows/commits/TIMOB-25019), we have been seeing that the app tend to suspend while we are executing our unit test. We might want to give developer a chance to control the extended execution manually by the new API. From cross-platform perspective the app suspension scheme has pretty much similar to what iOS/Android has I believe, so I think we still want to keep that parity too.
