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] Profile Lookup Events
Adds a Pre Lookup Event and a Post Lookup Event so that plugins may prefill in profile data, and cache the responses from
profiles that had to be looked up.
