K2: add package FQ name to ClassId of anonymous objects

This is needed because in order to figure out which declarations are
visible from anonymous objects in terms of overridability (see
`FirVisibilityChecker.isVisibleForOverriding`), we need to get the
package name of that anonymous object, because there's package-private
visibility on JVM.
