Track a second from_linter for lateral subqueries

Track a second from_linter for lateral subqueries

Fixed bug where the "cartesian product" assertion was not correctly
accommodating for joins between tables that relied upon the use of LATERAL
to connect from a subquery to another subquery in the enclosing context.

Additionally, enabled from_linting for the base assert_compile(),
however it remains off by default; to enable by default we would
have to make sure it isn't set for DDL compiles and there's also
a lot of tests that would also need to turn it off, so leaving
this off for expediency.

Fixes: #5924
