Parametric mapgen part 4: Support mapgen parameters for most mapgen ids

[jbytheway]

Summary

Infrastructure "Support mapgen parameters for most mapgen ids"

Purpose of change

Prior to this PR mapgen parameters only worked for terrain. This was simply a limitation to simplify the initial implementation. We want them to work for all the other things in mapgen also.

Continuing the work from #48529, #49980, #50681.

Describe the solution

Extend mapgen parameter support to most other mapgen ids. The few things that are not supported are:

• jmapgen_gaspump's fuel type
• jmapgen_item_group's item group
• jmapgen_loot's result_group
• jmapgen_monster's monster ids
• jmapgen_sealed_item's furniture id

Those are trickier cases which will need more careful attention, so I have left them for now.

Other changes that come along in this PR:

• More types for cata_variant (for each of the ids we are parametrizing).
• Migrate some zone definitions to JSON (because when they are hardcoded in the way that they were, their ids were invalid and couldn't be used in mapgen due to the sanity checks I added).
• Improve checks on parameter definitions. In particular, check that all values used are valid.
• Test the newly extended functionality by tweaking the definition of vents in the new modular labs by @curstwist. Previously the vents always blew cold air. Now they choose randomly between hot and cold, but the same across any specific lab. (In my mind you get hot air if the air conditioner has broken)

Describe alternatives you've considered

Trying to cover more of the awkward cases I chose to leave out.

Testing

Unit tests verify that the JSON still loads OK.

Some walking around in-world suggests that I haven't broken mapgen too comprehensively. I certainly haven't tested all the code I've changed, but I'm hoping the changes were similar enough that they should all behave similarly.

Debug-spawned the lab_mutagen_6_floor and verified that the vents seem to be behaving as desired.

Additional context

The way errors are reported for JSON mapgen will have changed as a result of this. Some errors should be improved while others have probably become worse (in particular, some now won't provide the nice line and column number with an extract of the problematic JSON), but overall I hope it's a net win. I'd like to figure out how to restore the previous error experience, but it's not obvious to me how, so I'm not attempting to do it in this PR.

I don't know what to put where "roof_type" is.
