Traps can directly trigger EoCs as their action

[Procyonae]

Summary

Infrastructure "Traps can directly trigger EoCs as their action"

Purpose of change

Triggering simple EoCs via spells is ugly and cumbersome

Describe the solution

Traps can trigger EoCs directly with the creature that triggers it as the alpha talker
Passes the trap's location as a context variable trap_location for use primarily with ranged traps
If triggered by an item passes the item's id as a context variable trap_item_trigger, so you can do cool silly stuff like puzzle switches where putting different key items on a trap does different things and you need to figure out the solution, with incorrect placement potentially having bad consequences (Erk posited something like this for nether dungeons before)
Documents the above
Unhardcodes the trap action "telepad" (and "portal" which was just an alias) bc I needed to write an EoC to test it anyway
Changes trap->spell->eoc to trap->eoc across the repo

Describe alternatives you've considered

Doing this in #77455 but it's not required for those changes and could do with a repo wide sweep up of existing pseudo EoC traps
I attempted items that trigger traps to be passed as talkers but couldn't get that to work, I considered falling back on passing a trap_item_trigger context var with the id of the item (and maybe another for it's translated name) but that would require passing an irrelevant talker like the player as you can't have 0 talker dialogues which seems very hacky. Will attempt to try this again if I think of anything

Testing

The tr_telepad works as expected with the player and Liam

Additional context

Firing EoCs via spells can still make sense if you want something complicated
