Refactors rocket launchers, adds it to nukie uplink (#21273)

* initial changes to rocket launcher

* moves the missiles to special projectiles

* gonna keep it real, im too high for mechcode

* missiles are now projectiles

* pt. 2 of last commit

* Now we don't need process fire to handle all this

* shoots you with my gun that makes you explode

* uplink time

* I hate mechs I hate mechs I hate mechs

* minor typo detected

* tech origin fix

* whoops the light ones explode twice

* THIS JUST MAKES IT WORK????

* maybe balance is a good thing

* Renamed ammo in uplink
