Migrate PGPROC's backendLock into PGPROC itself, using a new tranche.
Previously, each PGPROC's backendLock was part of the main tranche, and the PGPROC just contained a pointer. Now, the actual LWLock is part of the PGPROC. As with previous, similar patches, this makes it significantly easier to identify these lwlocks in LWLOCK_STATS or Trace_lwlocks output and improves modularity.
