This is in the same line as 08b9b9e043bb, down to v17. For
08b9b9e043bb, we were lucky enough to not be in GA, would people mind
to sneak this lwlock tranche name change in v17? In v16 and older
versions, we have been using MultiXactOffsetSLRU (documented), not
MultixactOffsetSLRU. So there is some history here.
