Summary

show grants panic when role/user has immute db/table privilege

The mutetable catalog mget need discard the immuteable db/table id.

If not, will generate vec out of index.

Easy way to reproduce

create role role3;
grant select on system.one to role role3;
show grants for role role3;

So in this pr, we split the db/table id in DatabaseCatalog
