Improve Light Queue and force enable it for all
There is no reason for the light queue to even be an option. This
enables the light queue for everyone.

This also improves the "can we still tick" time logic to always
check before running a light operation.

previously, we always executed at least 10 on the first world
(but not other worlds...), but we are seeing light take up some
heavy time, so improving that for now.

I've now also improved recheck gaps logic to happen at the end of all single block updates

This also prevents multiple gap checks, as previously if a tick skipped
the gaps check, the next tick would end up re-adding the entry again,
resulting in multiple gap checks.

This now just sets a marker "We need to recheck gaps" and will only occur
once.

This also should reduce chunk loads, as previously, we checked if
the neighbor chunks were loaded for the gap check, however those
neighbor chunks might of unloaded before the light queue operation
actually ran. Now, the neighbor chunk is done when the gap check
is being done, so it should avoid loading chunks.

Fixes #1466
Fixes #1431

Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk
In many places where we simply want the current chunk the entity
is in, instead of doing a hashmap lookup for it, we now have access
to the object directly on the Entity/TileEntity object we can directly grab.
Use that local value instead to reduce lookups in many hot places.
