refactor(component): use is a RequestUse message handler

Components no longer have a virtual OnUse; each component that reacts to a
use registers a RequestUse handler, like the client's components. The entity
runs the INTERACT trigger and the script, then delivers a RequestUseEvent
(carrying the user) to the handlers. The mission choice of a multi-interact
use goes only to the mission offer, as before. Switches keep a direct
EnterIfResponding for touches and pets.
