start of persistence support

[deltanedas]

About the PR

mini revival of #14740
lets maps be loaded from persistence saves and adds persistencesave command

this pr doesnt change any components to reserialize properly nor does it add the save load test as that wouldn't work at all.

more data will be saved in future prs piece by piece until eventually the test can be added and boom persistence can be used live.

Why / Balance

good

Technical details

the bool cvar game.usepersistence is used as before to control persistence being used at all.
with persistence enabled game.persistencestartmap map prototype is loaded.

with persistence game.map is no longer a prototype id but a path to a save file in the userdata directory.
if it exists, the MapPath on the start map prototype is replaced with this.

Media

a modified empty map saved and loaded on a fresh server
a few things are serialized properly :) like ame jar being in the controller, nodegroups probably and the akms bolt being closed.

• I have added screenshots/videos to this PR showcasing its changes ingame, or this PR does not require an ingame showcase

Breaking changes

no

I am aware of it but that doesn't necessarily mean it's not working. Especially, since the persistencesave command is still there and no other PR or post regarding this has been made. I'd really love to get this working as I try to save modified maps for our server.

you'd want to look at space-wizards/RobustToolbox#6166 for that then
