Optimize shared memory usage for WaitLSNProcInfo
We need separate pairing heaps for different WaitLSNType's, because there
might be waiters for different LSN's at the same time. However, one process
can wait only for one type of LSN at a time. So, no need for inHeap
and heapNode fields to be arrays.
