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] Add system property to disable book size limits
If anyone comes in with a watchdog crash related to books after this patch
you will not only be publicly shamed but also made an example of.
Disables the security limits on books entirely, allowing plugins AND players
to make books with as much data as they want. Do not use this without
limiting incoming data from packets in some other way.
