Improve description of some WAL records with transaction commands

This commit improves the description of some WAL records for the
Transaction RMGR:
- Track remote_apply for a transaction commit. This GUC is
user-settable, so this information can be useful for debugging.
- Add replication origin information for PREPARE TRANSACTION, with the
origin ID, LSN and timestamp
- Same as above, for ROLLBACK PREPARED.

This impacts the format of pg_waldump or anything using these
description routines, so no backpatch is done.
