Add resource statistics reporting to ANALYZE VERBOSE.
Previously, log_autovacuum_min_duration utilized dedicated code for logging resource statistics, such as system and buffer usage during autoanalyze. However, this logging functionality was not utilized by ANALYZE VERBOSE. This commit adds resource statistics reporting to ANALYZE VERBOSE by reusing the same logging code as autoanalyze.
