[REQUEST] `onSetupEntity` event for entities that is called via tactical_entity_manager at the end of the `setupEntity` function

[LordMidas]

Is your feature request related to a problem? Please describe.
In Reforged especially we like to add perks to entities depending on their equipment. The entities get assigned equipment during assignRandomEquipment and then if we have a separate event like onSetupEntity we can use that separate function to add perks depending on equipment.

This keeps the assignment of equipment separate from the assignment of perks, so if a submod of a mod wants to modify an entity's equipment, they don't have to copy the entire perks implementation too. They can simply overwrite the equipment function and let the main mod's perk assignment logic remain unchanged.

Describe the solution you'd like
Add an onSetupEntity event in actor.nut that is called at the end of the setupEntity funtion in tactical_entity_manager.

I'd rather have something more descriptive as a function name like afterEquipmentAssigned

I prefer onSetupEntity because it is called at the end of the setupEntity function, and isn't necessarily immediately after equipment assignment. The assignment of the equipment is one thing of many that happens during the setupEntity function. I would've been happy with afterEquipmentAssigned if it were called directly at the end of the assignRandomEquipment function.

I think the onSpawnEntity function as proposed in #372 is probably the solution that will cover this use case as well, so we probably don't need an onSetupEntity or onAfterEquipmentAssigned functions because I have a feeling these will miss certain edge cases (e.g. resurrection) which the onSpawnEntity impementation properly accounts for.
