feat: Add in-commit timestamp support for change data feed

[OussamaSaoudi-db]

What changes are proposed in this pull request?

This adds support for in-commit timestamps when performing change data feed. Now when a commit contains commitInfo with inCommitTimestamp, that timestamp will be the one used for all changed rows in the commit.

Depends on #581

Please only review these commits.

How was this change tested?

Add tests to check that the timestamp extracted from commits containing in-commit-timestamps are the ICT instead of file modification time.
