Jordan Dominion 3ceee2aab4 World Initialization Refactor (#74808)
- Removes unnecessary real global vars.
- Adds comments pointing to the init order defined in
/code/game/world.dm.
- Prevent people using `GLOBAL_REAL_VAR` and `GLOBAL_REAL` to circumvent
init order.
- Properly type `PROFILE_STORE` real global.
- Refactored `make_datum_references_lists()` and moved the call to it
into `GLOB` init with duct tape.
- Renamed `GLOB.admin_log` to `GLOB.admin_activities` as it wasn't
actually a log file.
- Whitelist loading happens in config.
- Renamed `SSdbcore`'s `SetRoundID()` to `InitializeRound()`. Now
handles calling `CheckSchemaVersion()`.
- Created macro for setting up log `GLOB`s.
- Removed log line for `GLOB` count.
- Moved call to `make_datum_reference_lists()` to
`/datum/controller/global_vars/Initialize()`. I slimmed it down where
possible too.
- Updated comments about world init order.
- Move `load_admins()` call to after log setup.
- Removes unused function `gib_stack_trace()`.
- Removes a bunch of unused log `GLOB`s.
- Unlocks the secrets of the universe by finally making the first
executed line of code deterministic.

No functional changes. Closes #74792
Testmerge thoroughly.
