Add WAL usage reporting to ANALYZE VERBOSE output.
This change adds WAL usage reporting to the output of ANALYZE VERBOSE
and autoanalyze reports. It aligns the analyze output with VACUUM,
providing consistency. Additionally, it aids in troubleshooting cases
where WAL records are generated during analyze operations.
