Add resource statistics reporting to ANALYZE VERBOSE.

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.
