Zach Brown 9bafd0634e Stop explicitly blocking Vanilla Method Profiler
At the time this was re-added, there was concern around how the JIT
would handle the system property that enabled it.

This shouldn't be a problem, and as such we no longer need to block
access to it.

The Vanilla Method Profiler will not provide much to most users however
there is no harm in providing it as an option. For most users, the
recommended and supported method for determining performance issues with
Paper will continue to be Timings.

Subject: [PATCH] MC-99321 - Dont check for blocked double chest for hoppers
etc
This is a source of MAJOR lag for hoppers, as well as a gameplay bug.
This removes the necessity to disable the cat on chest behavior to improve performance.
now performance will be improved even if you have cat chest detection on.
