Using the total number of users in the connection set
is not correct since those users may not be logged in
yet. Instead, track separately the number of users
who have passed the slot check.

The world tick will synchronise block data to clients. If
the connection tick is ran before, then the server will
send the block ack before the block updates - which causes
the client to think that any blocks it broke/placed
were rejected.

The data both store are caches which are cleared after updates,
which means that there is no block/position data being tracked
across ticks. As long as each region has its own instance, there
should be no cross-region data access.

Additionally, fix ActivationRange using global state to store
the AABBs it checks entities against. This fixes an issue where
entities would not be activated when they should be.
The region shift is configurable under `grid-exponent`, which
allows setting the region shift to any value in [0, 31]. Note
that values above 6 affect the lock shift, as the lock shift
currently is computed as max(ticket shift = 6, region shift).
The shift is left configurable for now as the lower default
shift of 2 may have negative performance impacts.
The default region shift has been adjusted to 2 from 4, and
the empty chunk buffer has been reduced to 8 from 16. These
changes reduce, but do not eliminate, player spread
requirements. The previous block range was around ~1500 blocks
at VD = 10, but is now closer to ~900 blocks at VD = 10. This
roughly reduces the area that each player uses in the regioniser
by 2.5x.
Currently, /tick is disabled but is planned to be re-added.
It's unlikely that support for sprinting can be implemented
precisely due to the fact that Folia ticks many regions
independently. However, a best-effort approach will be used.
