pg_dumpall: Skip global objects with --statistics-only or --no-schema.

Previously, pg_dumpall would still dump global objects such as roles
and tablespaces even when --statistics-only or --no-schema was specified.
Since these global objects are treated as schema-level data, they should
be skipped in these cases.

This commit fixes the issue by ensuring that global objects are not
dumped when either --statistics-only or --no-schema is used.
