Adds a speech modifier to pAIs on EMP (#46411)

About The Pull Request

Makes it so pAIs either stutter, slur, or talk like a brainlet when they're EMPed. This can be fixed by someone pressing the "Reset speech synthesis module" button on the pAI card. Additionally, adds a 40% chance for their default language to be swapped.
Readded the mute, albeit a bit shorter, due to feedback.

Why It's Good For The Game

Mutes are boring. This adds a debuff that while less severe, persists for longer and requires the help of another player to fix.
Changelog

tweak: pAI speech modules have been upgraded to be more EMP resistant, but they can now malfunction on EMP.
