Add relic activation ability

[anothersimulacrum]

Summary

SUMMARY: Features "Add activation abilities and charges to relics"

Purpose of change

Requested by @KorGgenT to further obsolete the artifact code.

Describe the solution

Encapsulate all the charge info about relics in a relic_charge_info struct - then allow specifying variations of this in the relic_procgen_data.

Add simple placeholder versions to this data, along with active effects for it to provide.

Attempt to recharge relics when processing them.

Testing

Spawn in a relic, activate it. See that it gives you pain. Wait for more than 6 hours, see that the relic has recharged.

Additional context

[KorGgenT]

This is an excellent start! I want these things for the procgen in order to be as flexible as possible:

• A "range" of max charges (the artifact spawns with a max charges of between x and y)
• a range of time (the artifact can recharge every z time which is between x and y)
• a range of charges_per_use
• these ranges are ranges in the procgen_data only, the artifact should have a singular number
• All of these should have power level values
• give active_procgen_values a power level as well, per spell
• in relic::power_level() and relic_procgen_data::power_level() add all these up

I believe all of these features will make for very well-rounded procedural generation rules for artifacts.

this is the only thing i encountered upon generating an artifact.
The other thing i mentioned on discord (artifacts not showing up in the a menu) imo could/should be a follow up PR and not block this PR from merging.

i don't know what's going on here.
