bufmgr: Separate keys for private refcount infrastructure
This makes lookups faster, due to allowing auto-vectorized lookups. It is also
beneficial for an upcoming patch, independent of auto-vectorization, as the
upcoming patch wants to track more information for each pinned buffer, making
the existing loop, iterating over an array of PrivateRefCountEntry, more
expensive due to increasing its size.
