[Feature] Snapshot script status just before crash

[YuLun-bili]

Is your feature request related to a problem (if not, explain why you think this feature should be added)? Please describe.

Crash caused by a script have no trace in log.txt (#553) or crash dump files, making this specific type of troubleshooting more difficult especially when happened on a normal player's pc with no/limited modding knowledge.

Describe the solution you'd like

Game could try to record last function called from script so that when a crash happened we at least could know what the game was doing. Recording script environment or arguments passed would be more helpful although I think these could be optional.

An example of what I'm expecting to see in log or crashdump when a crash happens can be:

--------------
CRASH DETECTED
--------------
last function call:
[.../Teardown/mods/Local test mod/test.lua]:27: Spawn()
parameters passed:
1: [string] "<vehicle/>"
2: [none] (using default)
3: [none] (using default)
4: [none] (using default)
check script_env_dump.txt for script environment

Describe alternatives you've considered

well alternatives are just what we have currently

Additional context

As I have limited knowledge on software development and crash handling, some ideas might be not practically possible.

@Gregory-Gregory Any news on this? I am currently trying to investigate a crash experienced by a subscriber of one of my mods, and without this I fear I will not be able to tell what's wrong with his game when it works perfectly fine on mine...

@FlorentP42 I checked with the team and get back to you if I get any answer regarding this.

Actually there may be some level of info printed already: I got this from the log.txt of the person I was talking about earlier:

This is not really Lua stack, but it is engine level error indicating some meory allocation failed which is already interesting. Combining this with Lua stack would be perfect :)

Also I opened https://github.com/Teardown-Issue-Tracker-Maintainers/Teardown-Issue-Tracker/issues/567 regarding the crash above, this does not seem right :p
