The owner of the projectile would need to be retrieved, which
may trip a thread check. We do not track ender pearls anyways,
so the registration logic does nothing regardless.

We cannot guarantee that the current region owns the chunk
associated with the ChunkData. As a result, more than 1 region
may write to the field.
Additionally, we did not include any logic to adjust the field during
a region merge or split - which would leave invalid data in the field.
As a result, the nearbyPlayers data retrieved from the ChunkData
was possibly invalid which may have lead to entity tracker desync
problems.

It is possible that when the reference count is retrieved that
the ticket updates have not yet been processed, which means
that the region section at the queued position may not exist or may
become nonexistant while or after the task is being added.
This restructures the reference counting code to now refer to
both a reference counter and a flag indicating whether ticket
updates are processed.

This issue shows the race condition where the region becomes
nonexistant.
If we cannot find a spawn pos in the spawn radius,
use the same fallback logic as when the world type or player's
gamemode does not support spawn selection. This adjusts the spawn
position to not be inside a wall or on water.
The spawn selection may actually be farther than 32 blocks,
so we need a larger load radius to prevent a deadlock on startup.
Additionally, re-insert thread checks for sync loads that were
previously in 1.20.
If a player moves away before the raid is created, then we would
possibly trigger the raid cross-region.
Considering Vanilla doesn't trigger the raid cross-dimension, this
doesn't seem like an important behavior to break.

CraftEntity properly tracks the underlying entity handle
when the entity teleports. This resolves a race condition
where if an enderpearl was ticked while its owner was teleporting,
the owner reference would be lost.

This field is covered by the entity tracker optimisations in Paper,
but currently was not properly maintained - resulting in memory leaks.
