Manuel Ung 8a678a50ba WriteUnPrepared: Relax restriction on iterators and writes with no snapshot (#5697) 
Summary:
Currently, if a write is done without a snapshot, then `largest_validated_seq_` is set to `kMaxSequenceNumber`. This is too aggressive, because an iterator with a snapshot created after this write should be valid.

Set `largest_validated_seq_` to `GetLastPublishedSequence` instead. The variable means that no keys in the current tracked key set has changed by other transactions since `largest_validated_seq_`.

Also, do some extra cleanup in Clear() for safety.
