This should greatly improve performance by using a No Op lock
while on the main thread.
Vanilla always had a write lock on write operations, but we added
a Read Lock during Async Chunks to make concurrent writes non fatal
for Async Chunks.
This means we added on a bunch of over head to all chunk read operations.
This corrects that, as well as disabling the write lock while on main thread.
It is a general rule that you do not touch a chunk async once it is loaded
into the world, as we never had locks on the chunk before 1.13 even.
So once we are on main, we don't expect concurrent access to begin with,
so we don't need the write locks either.

this has technically been a longer standing problem, but if an async
chunk loads after a chunk has been removed from the chunk map, it would
be treated as any other spare chunk and kept loaded until Chunk GC kicks in.
This fixes that, but also obsoletes ChunkGC in that anytime we load a spare
chunk (a chunk outside of any players view distance), we will immediately
mark it for unload.
This should reduce the amount of spare chunks loaded on a server.
