Allow EOCs to check and modify battery charge in items

[zachary-kaelan]

Summary

Infrastructure "Allow EOCs to check and modify battery charge in items"

Purpose of change

Fixes #74657

Describe the solution

Override the power_cur, power_max, and set_power_cur functions for talker_item, to make those functions work intuitively with items.

Describe alternatives you've considered

Make completely new functions.

You can.. stack multiple search_data objects of the same type? Holy mother of god i didn't even knew about it. Can you please document it somewhere with this examples?

It's an array, but the description used the singular condition and the examples didn't give any indicator that multiple conditions could be stacked. I think I only noticed it was an array because of errors when I didn't use an array.

I added some clarification to the documentation.
