50ad6c3131 New scheduler API 
Now, entity/global/location schedulers implement a generic run,
runDelayed, and runAtFixedRate methods that provide a ScheduledTask
value that can be used to interact with the scheduled task.

Add also an async task scheduler that implements the same methods,
except the delays/periods are in time and not ticks, as the scheduler
is independent of the server tick process.

Additionally, throw on some unimplemented APIs now.

0da953539b Disable mid-tick task execution 
Mid-tick task execution acquires the ticket lock at least,
which can possibly be a significant performance bottleneck
at a high tick thread + region count. This change should reduce
the impact from scaling the region threads, but is not a fix
to the underlying issue.

106a4affdc Suppress entire CB passenger events if the entity is not valid 
The event is not being called, so the checks will not do
anything. We need to bypass the checks so that we do not trip
the thread check.

a9a885ad00 Resolve concurrent access to ticket state 
The concurrent access occurred in the region merge/split logic,
as it did not own the ticket lock. To resolve this, we simply
make the ticket add/remove acquire the read lock of
the region lock.

760de0a276 Move region center calculation into try-catch 
Sometimes a region is empty, but only when the threaded regioniser

Additionally, only remove pending teleports after setting the
