ThreadUnsafeRandom is a random implementation that is
identical to LegacyRandomSource behaviourally, but
without the thread checks.
SimpleThreadUnsafeRandom is ThreadUnsafeRandom except with
its nextInt(int) function replaced with a faster
but more biased implementation when bound is very large.
Additionally, replace Level/Entity randoms with ThreadUnsafeRandom.
This avoids the expensive CAS logic at the expense of losing the
thread check.
This method should be present in Paper, not just in Folia, given
that the GlobalRegionScheduler is present.
Additonally, add Server#isOwnedByCurrentRegion(World, int, int, int, int)
for checking of a rectangle of chunks is owned by the current region.
Spigot incorrectly returns false in Wolf#actuallyHurt if the armor
absorbed the damage causing the entity to not get damage invuln ticks.
Resolve this by correctly reverting to the "always true" return value as
the event is not cancelled.

Fixes incorrect spigot handling of the invulnerability damage
reduction applied when an already invulnerable entity is damaged with a
larger damage amount than the initial damage.
Vanilla still damages entities even if invulnerable if the damage to be
applied is larger than the previous damage taken. In that case, vanilla
applies the difference between the previous damage taken and the
proposed damage.
Spigot's damage modifier API takes over the computation of damage
reducing effects, however spigot invokes this handling with the initial
damage before computing the difference to the previous damage amount.
This leads to the reduction values to generally be larger than expected,
as they are computed on the not-yet-reduced value.
Spigot applies these reductions after calling the EntityDamageEvent and
*then* subtracts the previous damage point, leading to the final damage
amount being smaller than expected.
This patch cannot simply call the EntityDamageEvent with the reduced
damage, as that would lead to EntityDamageEvent#getDamage() returning
the already reduced damage, which breaks its method contract.
Instead, this patch makes use of the DamageModifier API, implementing
the last-damage-reduction as a DamageModifier.
