PG-234: Fix loading both pg_stat_monitor and pg_stat_statements.

Browse Source 
If both modules are loaded then pg_stat_monitor detects that and avoid
calling standard_ProcessUtility() in ProcessUtility_hook hook, as
calling it twice is an error and triggers an assertion on PostgreSQL.

On PostgreSQL 13, pg_stat_monitor must be loaded after
pg_stat_statements, as pg_stat_statements doesn't do such verifications,
it end calling standard_ProcessUtility() and other functions even if
another module is registered, that is an error.

They fixed this problem with pg_stat_statements in PostgreSQL 14 and onward.
