Manuel Ung 66b524a911 Simplify WriteUnpreparedTxnReadCallback and fix some comments (#5621) ...

Summary:
Simplify WriteUnpreparedTxnReadCallback so we just have one function `CalcMaxVisibleSeq`. Also, there's no need for the read callback to hold onto the transaction any more, so just hold the set of unprep_seqs, reducing about of indirection in `IsVisibleFullCheck`.

Also, some comments about using transaction snapshot were out of date, so remove them.
