Fix volatility marking of commit timestamp functions
They are marked stable, but since they act on instantaneous state and itis possible to consult state of transactions as they commit, the resultscould change mid-query. They need to be marked volatile, and thiscommit does so.There would normally be a catversion bump here, but this is so much aniche feature and I don't believe there's real damage from the incorrectmarking, that I refrained.Backpatch to 9.5, where commit timestamps where introduced.Per note from Fujii Masao.
