RLS: Store module defined RLS queries in system table

[joshua-spacetime]

This ticket includes (1) creating a system table for RLS queries, and (2) updating the drivers of __describe_module__ (database init and update) to insert RLS queries into this system table.

Note, the module should fail to compile if the queries fail to compile.
