Create talker item, paving way for greater item json interactions.

[Ramza13]

Summary

Infrastructure "Create talker item, add consumption_eocs"

Purpose of change

Allow item EOC's to run functions on the item. At present location functions and allowing setting and accessing variables are the only supported functions.
Add consumption_eocs, effect on conditions run after consuming an item.

Describe the solution

talker_item has been a to-do for a number of projects and here is a basic version. This is a step towards having a conversation with an item.
Also part of my goal of creating migo bio technology. I want each piece to use a random function that once assigned doesn't change or does so in a controlled manner. So they all have the same name and you don't know what you are getting.

There has been discord talk of creating books with random quotes that don't change, this is a piece of that or even the whole thing if you are a masochist.

Also added consumption eoc's. These are for #35882. They are just effect_on_conditions run after consuming something. They are the second commit and could be seperate but are small and use talker_item.

Testing

Played around with this json

{
    "type": "effect_on_condition",
    "id": "EOC_1",
    "condition":{ "not":{"npc_has_var": "npc_foodperson_impressed", "type": "dialogue", "context": "foodperson", "value": "yes" }},
    "effect": [ { "message": "You feel very testy" }, { "npc_add_var": "npc_foodperson_impressed", "type": "dialogue", "context": "foodperson", "value": "yes" } ]
  },
  {
    "type": "effect_on_condition",
    "id": "EOC_2",
    "condition":{ "npc_has_var": "npc_foodperson_impressed", "type": "dialogue", "context": "foodperson", "value": "yes" },
    "effect": [ { "message": "You score!" } ]
  },
  {
    "id": "test",
    "type": "TOOL",
    "name": { "str_sp": "test" },
    "description": "A test.",
    "weight": "1 g",
    "volume": "250 ml",
    "price": 3000,
    "price_postapoc": 10000,
    "symbol": "!",
    "color": "light_red",
    "use_action": {
      "type": "effect_on_conditions",
      "description": "Test.",
      "effect_on_conditions": [ "EOC_1", "EOC_2" ]
    }
  },

For consumption eocs just add the line: "consumption_effect_on_conditions":["EOC_SLEEP"],
to a food. I did protein_bar_evac since thats where this is planning to be used.
