[FIR] Properly check for visibility in FirTypeIntersectionScopeContext

This fixes a false positive OVERRIDING_FINAL_MEMBER caused by a
package-private member in a different package being added to the
list of overridden symbols. However, in Java, package-private members
from different packages are effectively like private members in that
they cannot be overridden.
