Fix chunk force ticking

[Matyrobbrt]

In 1.21.2, Mojang changed the previous chunk ticking code. Instead of iterating all known chunks and checking if each one should be ticked, it now uses a chunk manager that's constantly based on the location of players.

This means that our previous code which simply adds a check on the ticking candidates is no longer feasible, as chunks situated far out from players will not even be considered candidates to begin with. The new method adds each force ticked chunk to the list of final candidates manually, checking if the chunk is already in the list.

Fixes #1702
