2 people had issues where some plugin is doing some reallly insane NMS hackery
that created invalid worlds, which caused some errors...
Really don't understand what in the world they did, but putting in a dumb guard that
shouldn't even be necessary to just not send the sound effect rather than erroring.
While this method has async in it's name, it's not actually meant
to be called asynchronously.... It just means IT will load the chunk
asynchronously without blocking main.
So fix this so that if a plugin calls it async, it forces the request back to main thread.
Blow up if a plugin tries to mutate visibleChunks directly and prevent them
from doing so.
Also provide a safe get call if any plugins directly call get on it so
that it uses the special logic to check pending.
Also restores ABI for the visibleChunks field back to what it was too.
Additionally, remove the stack trace from Timings Stack Corruption for any
error thrown on Minecraft Timings, and tell them to get the error ABOVE this
instead, so people stop giving us useless error reports.
Also fixes a memory leak when the source map down sizes but dest map didn't,
which resulted in lingering references to old chunk holders.
Fixes#3414
Fixed a few bugs, and made numerous improvements.
Fixed issue where a sync chunk load could have its ticket removed and the
priority ticket could expire...
Still not perfect there but better than before.
Also fixed few other misc issues such as watchdog cpu usage, chunk queue update
had risk of double enqueue due to it no longer being a set.
Added much more information about chunk state to watchdog prints.
I see some more room for improvement even, but this is much better than before.

Mark chunks that are blocking main thread for world generation as urgent
Implements a general priority system so that chunks that are sorted in
the generator queues can prioritize certain chunks over another.
Urgent chunks will jump to the front of the line, ensuring that a
sync chunk load on an ungenerated chunk does not lag the server for
a long period of time if the servers generator queues are filled with
lots of chunks already.
This massively reduces the lag spikes from sync chunk gens.
Then we further prioritize loading order so nearby chunks have higher
priority than distant chunks, reducing the pressure a high no tick
view distance holds on you.
Chunks in front of the player have higher priority, to help with
fast traveling players keep up with their movement.
This commit also improves single core cpu scenarios in that we will
now automatically disable Async Chunks as well as Minecrafts thread
pool.
It is never recommended to use async chunks on a single CPU as context
switching will be slower than just running it all on main.
This also bumps the number of server worker threads by default too.
Mojang does not utilize the workers in an effecient manner, resulting
in them using barely any sustained CPU.
So give it more workers so more chunks can be processed concurrently
This change also improves urgent chunk loading, so players flying into
unloaded chunks will hurt a little bit less (but still hurt)

This also cleans up the implementation of Async Chunks to get rid of most
Consumer callbacks and instead return futures.
This lets us propogate errors correctly up the future chain
(barring one isn't lost even deeper in the chain...)
So exceptions can now bubble to plugins using getChunkAtAsync
