feat(mods): Obsolete no_global_uniques in favour of a RESPECT_GLOBALLY_UNIQUE world option

[Procyonae]

Purpose of change (The Why)

Closes #6757

Describe the solution (The How)

If RESPECT_GLOBALLY_UNIQUE is set to false GLOBALLY_UNIQUE (max one per world) specials are instead treated as though they're UNIQUE (max one per overmap)
They're still tracked as being placed in case you turn it back on mid save
Obsolete no_global_uniques mod as it's superceded by the option and errorlessly remove it

Describe alternatives you've considered

I attempted to migrate the new option to false if you had the mod for an updating world but it's not convenient to inject that in the place where BN does mod replacements due to call order and I didn't want to scope creep into trying store it and alter it later (the reverted commit does change the setting to false but also pops up an error and loses other non default world settings)

Testing

Changed cabin_lapin to be [99, 100] occurances and have a unique omt name to make it easily searchable
Genned a default world, found one cabin_lapin in ~16 overmaps as expected
Genned a world with RESPECT_GLOBALLY_UNIQUE set to false, found 2 cabin_lapin's in 5 overmaps

Additional context

Cloned BN so I can port the not yet merged rainbows to DDA and figured I might as well nab an easy C++ PR while I'm here

Checklist

Mandatory

• I wrote the PR title in conventional commit format.
• I ran the code formatter. (Hoping the DDA astyle is equiv)
• I linked any relevant issues using github keyword syntax like closes #1234 in Summary of the PR so it can be closed automatically.
• I've committed my changes to new branch that isn't main so it won't cause conflict when updating main branch later.

sorry, could you be more specific? even after increaing occurances to [99, 100] i wasn't able to find any "cabin" in overmap. how do i give it a unique name?

Code looks good at a glance.

1. Compiled and load-tested.
2. Spawned at refugee center, had no issues finding it.
3. Temporarily set them to be a 100% mandatory special, started debugging across multiple overmaps and did not find a second one.
4. Went back and set the option off.

Problem: even though I set occurrences to 1/1 for refugee centers to test a world where global specials were definitely set to off, which SHOULD force an appearance of the refugee center in every single world, I'm still not finding more than one after having visited several overmaps.
