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] use CB BlockState implementations for captured blocks
When modifying the world, CB will store a copy of the affected
blocks in order to restore their state in the case that the event
is cancelled. This change only modifies the collection of blocks
in the world by normal means, e.g. not during tree population,
as the potentially marginal overheads would serve no advantage.
CB was using a CraftBlockState for all blocks, which causes issues
should any block that uses information beyond a data ID would suffer
from missing information, e.g. Skulls.
By using CBs CraftBlock#getState(), we will maintain a proper copy of
the blockstate that will be valid for restoration, as opposed to dropping
information on restoration when the event is cancelled.
