RM13 premature shutdown fix, the Sequel: I need to learn how to Github better

Summary

Bugfixes "Fixed RM13 premature shutdown issue"

Purpose of change

Fixes #76926

Describe the solution

Adjusted the logic of the USE_POWER_WHEN_HIT if block in armor_absorb() so that instead of checking if the amount of incoming damage converted to kJ is greater than the amount of energy consumed by that attack, then deactivating, incoming damage in kJ is compared to the amount of energy remaining.

Added a new bool to energy_remaining() to allow for only checking the item's batteries, excluding UPS, bionic power and vehicle power.

Describe alternatives you've considered

1.) Letting someone more competent than I am fix it.
2.) Making the else block a more explicit else if block that checks if the incoming damage is less than the remaining energy. Just an if block was causing a drain on the suit when off. Made check explicit.

Testing

Loaded the save provided in #76926 with my proposed fix, held the wait button until the armor shut down at the appropriate time, opened up the log and observed the expected unique shutdown message was present.

Additional context

Somehow accidentally closed #76987 while dealing with merge conflicts.

Leaving this as a draft for the moment for feedback and in case I'm missing something.

TODO: add check in energy_remaining calls for either UPS or bionic energy toolmods to cover future use cases.
Eh. Do this in a future PR.
