Persistent Jobs mod compatibility

[T3M8029]

Introduced task destination track and car updates which the server gets by listening to events from PJ and the sends out to all clients.
Reworked the way clients get jobs, they can now ask for generation or for a specific jobs data.
Made car plate updates use a coroutine to resolve stuttering on entering a station (beware, the updates will wait for all cars there to be loaded).
Added an "absolute" ClientboudCouplingStatePacket that is sent on RestoreCarConections() (needed for PJ´s car resuming).
Made the clients use JobsManager for (un)registering jobs so other mods (eg. RD) can read job data.

Everything seems fine from my testing using this modset (both client and server).

Don´t want to bother you with this too much since I know there´s limited time, but I think that there won´t be any more changes to this needed from me, as it´s only the PJ side that´s giving problems. So whenever/if you end up having the time for it, you can merge it.
