Fix mesecons_gamecompat mvps hardcoding issues and increased game compatibility

[mruncreative]

Fixes #699
Registers mvps stoppers for all door and bed nodes registered using beds, mcl_beds, doors, mcl_doors mods.
In mtg trapdoors have the group door and need to be obtained through the api while beds don't have a registered_beds and need to be detected by their group.
In mcl_doors, doors and trapdoors have separate groups and no mcl_doors.registered_doors table.
The wooden trapdoor was not an mvps stopper, so I removed the other trapdoors from being mvps stoppers for no reason.

The checks fail because I used core instead of minetest somewhere and it's not specified as global to luacheck.

[mruncreative]

I have moved mesecons_doors to gamecompat.
Reasoning:

1. Gamecompat already does compatibility with doors.
2. Mesecons Doors provides no API
3. Mesecons Doors is a subpackage of Mesecons while having a hard dependency on doors
4. Point 3 makes Mesecons harder to enable outside of mtg
5. Point 3 makes Mesecons be listed as incompatible with non-MTG games on ContentDB

Check / Luacheck (pull_request) is currently failing because .luacheckrc lacks the core table, which is identical to minetest.

The bit module is missing from the testing container. I don't think I can fix that on my end.

The trapdoors are missing. Is this intentional? If not --> loop through doors.registered_trapdoors to add those nodes.

Discussed in #699 and I mentioned it on IRC. I thought you'd have seen it.

The wooden trapdoor was not an mvps stopper, so trapdoors in general do not need to be mvps blockers and sfan5 said the metal trapdoors were mvps stoppers because they can be locked. I think they can be dug though if they aren't protected. What is your take on that?
If you don't like it, I will add the metal trapdoors from MTG back to the hardcoded list.

Unlike doors and beds moving a trapdoor doesn't break anything after all. The locked chests are different from the trapdoors because their value is in what's inside and they can't be dug in MTG while having content.

Edit: Seems I'm wrong. They are owned even without me making a key. I added them back to the list.

Are you referring to the following message? https://irc.minetest.net/luanti/2025-01-31#i_6239224 Unfortunately I haven't seen that one.
Doors may glitch out, thus those should be stopper nodes. As for trapdoors - I am not sure, hence my question above whether this change was intentional. I suppose either way would be okay.

Works for me. Tested with Minetest Game. Looks good. Will merge in a few days unless there are objections.

[SmallJoker]

Squashed manually before merge. It was quite messy. Anyway. Thanks for the contributions.
