Converts `/datum/player_details` into `/datum/persistent_client`.
Persistent Clients persist across connections. The only time a mob's
persistent client will change is if the ckey it's bound to logs into a
different mob, or the mob is deleted (duh).
Also adds PossessByPlayer() so that transfering mob control is cleaner
and makes more immediate sense if you don't know byond-fu.
Clients are an abstract representation of a connection that can be
dropped at almost any moment so putting things that should be stable to
access at any time onto an undying object is ideal. This allows for
future expansions like abstracting away client.screen and managing
everything cleanly.
* Micro-optimize qdel by only permitting one parameter (#80628)
Productionizes #80615.
The core optimization is this:
```patch
- var/hint = to_delete.Destroy(arglist(args.Copy(2))) // Let our friend know they're about to get fucked up.
+ var/hint = to_delete.Destroy(force) // Let our friend know they're about to get fucked up.
```
We avoid a heap allocation in the form of copying the args over to a new
list. A/B testing shows this results in 33% better overtime, and in a
real round shaving off a full second of self time and 0.4 seconds of
overtime--both of these would be doubled in the event this is merged as
the new proc was only being run 50% of the time.

* Adds error on qdeling callback, fixes errors this causes (#77850)
## About The Pull Request
You shouldn't ever qdel a callback. If you don't want to own it free
your ref (remove it from a list/set it to null). When all refs are
cleared it'll get cleaned up by byond itself
* Adds error on qdeling callback, fixes errors this causes
