Support column-versions of all permission filter operators

The selection of permission BoolExp operators that support column values on their rhs seems quite arbitrary. For example, why support `_like` but not `_clike`?

Looking at the code, it looks like implementing more column operators might be as simple as a very mechanical update to [the parser](https://github.com/hasura/graphql-engine/blob/a63fa18d9c2f96917966a8df3168d15b1b490267/server/src-lib/Hasura/Backends/Postgres/DDL/BoolExp.hs) and [the translator](https://github.com/hasura/graphql-engine/blob/a63fa18d9c2f96917966a8df3168d15b1b490267/server/src-lib/Hasura/Backends/Postgres/Translate/BoolExp.hs).
