Subject: [PATCH v1] Refactor replication origin state reset helpers

Factor out common logic for clearing per-transaction and per-session
replication origin state into dedicated helper functions.

This removes duplicated assignments of replorigin_session_origin,
replorigin_session_origin_lsn, and replorigin_session_origin_timestamp
across multiple call sites, and makes the intended scope of each reset
(clear per-transaction state vs. clear per-session state) explicit.

No functional change intended.
