Implemented Electromorphosis' effect

Also added a battle preproc config to check if the STATUS3_CHARGED_UP was already applied.
Pokémon Scarlet and Violet don't check if this status flag was already applied on the target of abilities like Electromorphosis (and Wind Power until proven otherwise.)
As a result, the game will trigger the ability multiple times if they're hit by a multihit move.
This directive makes the code end the ability effect preemptively if the target does have the status flag applied.
