Subject: [PATCH] Improve and expand AsyncCatcher

Log when the async catcher is tripped
  The chunk system can swallow the exception given it's all
  built with completablefuture, so ensure it is at least printed.

Add/move several async catchers

Async catch modifications to critical entity state
  These used to be here from Spigot, but were dropped with 1.17.
  Now in 1.17, this state is _even more_ critical than it was before,
  so these must exist to catch stupid plugins.
