[demo] Add a way to crash the application

[breedx-splk]

Not sure where to put it, but could be nice to have a menu item or a button on a fragment in the shop activity that causes the app to crash. This allows us to manually test the crash detection instrumentation.

For starters, we can just pick whatever crash mechanism we like and if we want to try other ways in the future we can do that.

hi @breedx-splk assign this to me

It would be nice to track both JVM crashes and process terminations caused by the native layer - or something that simulates OS termination

@bidetofevil this got auto-closed when #584 was merged. If you feel strongly about the native bits, can you open a new issue for that? I'd also appreciate some clever ideas on how to simulate that. 😁

Will do!
