Use Last Access Cache for isLoaded calls
this should provide a pretty good across-the-board performance
improvement for the entire server, as it's very common for code
to check if (isLoaded(x, z)) { then do something on that chunk }

Previously, containsKey would not read or set the last access cache

By making it do get() != null, we gain the benefits of last access
and also improves thread safey for async isLoaded checks

This exact usage scenario is used in Entity movement, so that alone
saves us up to 5%~ of CPU time for Entity movement.

Ensure chunk neighbor counts do not get desynced
Mojang was not checking that the chunk did not overwrite, or
was successfully removed.

We're seeing odd reports in #1561 that indicates issues around
this are having problems.
