ACL SQLs should have single statement even if multiple roles used

Describe the bug

When an ACL is executed for multiple roles in a single statement, then the RE-SQL should also be a single statement

To Reproduce

Steps to reproduce the behavior:

1. Create a view viewtest

CREATE VIEW public.viewtest
 AS
select * from pg_class;

2. Execute the SQL assuming you have 2 roles - role1, role2:

GRANT UPDATE(oid) ON public.viewtest TO role1, role2;

3. Go to SQL tab. It shows

GRANT UPDATE(oid) ON public.viewtest TO role1;
GRANT UPDATE(oid) ON public.viewtest TO role2;

Expected behavior
The RE-SQL should also be a single statement. Apart from view, other places table, mview should also be checked.

Screenshots

Start by reproducing the SQL tab output for a view using the multi-role GRANT shown in the issue, then trace the ACL SQL generation path. Done means the reverse SQL uses one statement with both roles and the same behavior is checked for tables and materialized views.
