Fix NPE on TileEntitySkull (#3598)
The setGameProfile method on TileEntitySkull is annotated with the @nullable annotation,
but the skull didn't check for null profiles before attempting to retrieve cached skin.
This bug was introduced by the commit making the skull use spigot's User Cache.

Additionally, CraftMetaSkull also had the same issue with a null GameProfile, so this also
ensures it doesn't break.

The whole CraftPlayerProfile class is not null-safe, it requires a GameProfile that isn't
null so we add a Validation on the constructor, that way it is easier to catch this kind
of issue in the future.

Only complete from cache if ID is given (#3591)
As it stands, one can complete from the cache if no ID is given. If
there is no ID, it will throw an NPE, as ConcurrentHashMap (which is used
in UserCache) does not support null keys. This should fix any current
and future issues where exceptions are thrown just because a UUID is not
currently given on the profile due to a plugin or server bug/issue.

Fixes #3590.

Make Skull Texture Lookup use the User Cache
Spigots cache only cached by name which really was not correct...

Additionally, user cache exposes a cache of any player who has logged in
once this session too even if offline.

Also fixed some quirks with Profile API where we might of had textures
in the cache that we didn't even try to look up.

So this should overall help reduce API calls to Mojang.

Sadly, the User Cache doesn't cache textures, but if that ever
changes in future, we would gain benefit there too.

Improve Chunk Prioritization and Internal Scheduler
In previous MC versions, we had a rather simple internal scheduler
for delayed tasks that would just keep pushing task back until desired
tick was reached.

The method it called to schedule the task changed behavior in 1.14, and now
this scheduler is not working nowhere near what it was supposed to be doing.

This was causing long delayed task to eat up CPU (In Oversleep for example)

Rewrite this to just use the CraftScheduler for scheduling delayed tasks.

Once this was fixed, it became quite clear the code that delayed ticket
additions for chunks based on distance was clearly not right, as it was
tested on the previous broken logic.

So the ticket delay process has been vastly revamped to be even smarter.
Chunks behind the player can load slower than the chunks in front of the player.
We also can delay ticket adding until one of its neighbors has loaded, as
this lets us get a smoother spiral out for the chunks (minus frustum intent).

Additionally on frustum previous commit inadvertently broke frustum trying to
fix an issue when the real fix lied elsewhere, so restore chunk priority so
it works again.

More Improvements to Chunks
Fixed issues where urgent and prioritized chunks didn't actually
always get their priority boosted correctly....

Properly deprioritize non ticking chunks.
Limit recursion on watchdog prints to stop flooding as much
Remove neighbor priorities from watchdog to reduce information
reduce synchronization duration so that watch dog won't block main should main actually wake up
probably fixed a deadlock risk in watchdog printing also that was leading to crashes
fixed chunk holder enqueues not being processed correctly
added async catchers in some locations that should not be ran async

Fixed upstream bug where VITAL callbacks that must run on main actually could
sometimes run on the server thread pool causing alot of these nasty bugs we've seen lately!

This build will provide massive improvements to stability as well as even faster
sync chunk load/gens now that priority is correctly set.

Fixes #3435

Implement Chunk Priority / Urgency System for Chunks
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)

Ping #3395 #3363 (Not marking as closed, we need to make prevent moving work)

Foundational work for Future Memory usage improvements
This commit doesn't do much on its own, but adds a new Java Cleaner API
that lets us hook into Garbage Collector events to reclaim pooled objects and
return them to the pool.

Adds framework for Network Packets to know when a packet has finished dispatching
to get an idea when a packet is done sending to players.

Rewrites PooledObjects impl to properly respect max pool size and remove
almost all risk of contention.

Bumps the Paper Async Task Queue to use 2 threads, and properly shuts it down on shutdown.
