Introduce pg_signal_autovacuum_worker.

Since commit 3a9b18b309, roles with privileges of pg_signal_backend
cannot signal autovacuum workers.  Many users treated the ability
to signal autovacuum workers as a feature instead of a bug, so we
are reintroducing it via a new predefined role.  Having privileges
of this new role, named pg_signal_autovacuum_worker, only permits
signaling autovacuum workers.  It does not permit signaling other
types of superuser backends.

Bumps catversion.
