Tim b1a793f840 Refactor and improve antimagic to be more robust (#64124)
This refactors the antimagic component to use and have bitflags, documentation, defines, code comments, named arguments, and renames variable names for clarity. 

- /obj/effect/proc_holder/spell/aoe_turf/conjure/creature/cult is not used anywhere and has been removed
- /obj/effect/proc_holder/spell/targeted/turf_teleport/blink/cult is not used anywhere and has been removed

- New sound effects are played when magic is blocked. Depending on the type of magic being used it will be either:

- Equipping antimagic now properly updates the magic buttons
- Any magic being blocked or restricting casting now displays a message
- MAGIC_RESISTANCE_MIND now properly blocks telepathy effects
- Removes blood splatter when fireball is blocked
- Magic projectiles for staff of locker no longer spawn lockers when blocked by antimagic
- Fire breath is no longer blocked by antimagic
- Spellcards are now blocked by antimagic

Any antimagic on a mob blocks that magic type from being casted. (certain spells such as mime abilities completely ignore antimagic)

- Foilhats prevent someone from casting mind magic (telepathy, mindswap, etc.)
- Bibles, ritual Totems, nullrods, holymelons, and TRAIT_HOLY prevent someone from casting unholy magic (cult spells, etc.)
- Nullrods, ritual totem, and holymelons prevent someone from casting wizard magic (fireball, magic missile, etc.)
- Immorality talismans, berserker suits, and TRAIT_ANTIMAGIC prevents all types of magic (except stuff like mime abilities)
- Touch of Madness and Mindswap is now blocked with MAGIC_RESISTANCE and MAGIC_RESISTANCE_MIND
- Voice of god is now blocked with MAGIC_RESISTANCE_HOLY and MAGIC_RESISTANCE_MIND
