Core/Scripts: Change PlayerScript and CreatureScript inheritance (#23048)

Remove UnitScript from PlayerScript and CreatureScript classes as that's how the original system that was PR'd worked, see https://github.com/TrinityCore/TrinityCore/pull/7867 for reference.
Please note these are used as global hooks and should really just invoke stateless functions.
If you need to hook methods from PlayerScript/CreatureScript and UnitScript, just define 2 different scripts (this is how the original system worked and how it was designed to work)
