Michael Paquier d1bf86a622 Revert recent changes related to handling of 2PC files at recovery

This commit reverts 8f67f994e8 (down to v13) and c3de0f9eed (down to
v17), as these are proving to not be completely correct regarding two
aspects:
- In v17 and newer branches, c3de0f9eed38's check for epoch handling is
incorrect, and does not correctly handle frozen epochs.  A logic closer
to widen_snapshot_xid() should be used.  The 2PC code should try to
integrate deeper with FullTransactionIds, 5a1dfde833 being not enough.
- In v13 and newer branches, 8f67f994e8 is a workaround for the real
issue, which is that we should not attempt CLOG lookups without reaching
consistency.  This exists since 728bd991c3, and this is reachable with
ProcessTwoPhaseBuffer() called by restoreTwoPhaseData() at the beginning
of recovery.

Per discussion with Noah Misch.
