Validate ForceCrash capturing

[bitsandfoxes]

Let's validate we correctly capture crashes coming through Utils.ForceCrash on all platforms.
Let's even add a new scene just for those as users are more likely to try to crash the app through the helper function than to write their own C plugin.

The ForcedCrashCategory includes

AccessViolation
FatalError
Abort <- This one might be tricky since Unity itself is doing some Unity shenanigans there and not forwarding the crash
