wookieejedi 78d2e663d7 One fix and one enhancement to AI shield behavior (#6737)
* One fix and one enhancement to AI shield behavior

This PR adds one fix and one enhancement to AI shield behavior.

1) Fix: Testing, especially in FotG, revealed an edge-case bug with shield management where the AI will not direct shield energy to a quadrant if it was hit when that quadrant was down. In other words, if a shield quadrant is knocked down to 0 and continues to be shot the AI will not realize it needs to direct energy to that quadrant. This is because `quadrant` is set to -1 if a shield segment is down. This ensures that the resulting effects and damage calculations properly ignore that quadrant downstream, but it also results in `aip->last_hit_quadrant` being set to -1. This PR adds a fix to properly record which shield was actually hit, so that the AI knows to direct energy to that quadrant.

2) Enhancement: In combat situations with fire coming from many directions, it is good practice to keep shields equalized, so this PR adds a flag for the AI to always attempt to balance shields, even if it is being fired upon (instead of the current behavior to always direct energy to the hit shield quadrant).

Both flags are tested and work as expected.

* fix copy paste

* rename to avoid previous confusion

* also make as ai class flag
