Subject: [PATCH] Remove the Vanilla Method Profiler
Spigot rebrought this back after it was removed for years due to the performance hit.
It is unknown if the JIT will optimize it out as efficiently with how it was
added, so we do not want any risk of performance degredation.
Paper has a proper Timings system that makes the Vanilla Method profiler obsolete and inferior.
