We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
Consider call chain `foo.bar.baz()` which has expected type `Int`
Elements `foo` and `bar` doesn't have expected type `Int`,
this is especially important in NI, because we use expected type for
candidate applicability
