Yu Zhang 552bc01669 Surface timestamp from db to the transaction iterator (#11847)
Summary:
Provide an override implementation of `Iterator::timestamp` API for `BaseDeltaIterator` so that timestamp read from DB can be surfaced by an iterator created from inside of a transaction.

The behavior of the API follows this rule:
1) If the entry is read from within the transaction, an empty `Slice` is returned as the timestamp, regardless of whether `Transaction::SetCommitTimestamp` is called.
2) If the entry is read from the DB, the corresponding `DBIter::timestamp()` API's result is returned.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11847

Test Plan:
make all check
add some unit test
