city_sizes restriction for city buildings

[Procyonae]

Summary

Balance "City buildings are restricted to spawn in (more) appropriately sized cities"

Purpose of change

Addresses #72795 but that issue has interesting discussion on close future changes so I'd rather keep it open for now

Describe the solution

Allows city_sizes to be used with city_building specials

Adds usage to some existing buildings. Wants to be expanded on in future and the numbers used tweaked after more playtesting, currently the min sizes are very forgiving based on even the larger ingame "cities" at base urbanity being small in general. Weights of now restricted buildings might also want buffing. Some buildings could do with lower/higher density versions adding so city sizes that don't make sense for one kind still have good variety.

I were going to update documentation but can't even find any saying this field didn't work for city specials before

Describe alternatives you've considered

Doing this sooner
Originally I were going to include houses in this but I think they'd be better dealt with by splitting the houses "zone" into low/medium/high density and restricting their placement both on how central the placement is compared to the city centre and edge and the raw size. I'll add this in a follow up PR. This PR is better for specific building restrictions.
Not decided what to do with shops yet, I like the idea of districts discussed in #72795 but with how cities place currently that wouldn't be easy to add in a way that looks good, specialised streets could be quite doable tho.

Testing

Made mall spawn very frequently but only in size >= 12 cities.
Expected outcome.
The overmap coverage test might not like this, will run locally a bunch of times

Additional context

Nice work Procyonae. What sort of tagging will be needed for the overmap locations themselves? Stadiums for example.

The city_sizes field here will be added to the stadiums city_building entry below

ooh. I was going to do this but I'm quite okay that I don't have to.
