The inter-module interaction was partially supported, but the
DiagnosticCompilerTestFE10TestdataTestGenerated and
LFirPreresolvedReversedDiagnosticCompilerFE10TestDataTestGenerated were
failing. This is because the arguments of annotations were not fully
resolved in loadExperimentalitiesFromAnnotationTo function.

At the moment, SubclassOptInRequired is marked with the
ExperimentalSubclassOptIn annotation. However, it does not work
as expected due to a missing opt-in error. To use SubclassOptInRequired,
an explicit opt-in is necessary because SubclassOptInRequired is an
unstable feature now.

Previously, if the parent class was in Java code and the subclass in
Kotlin, the opt-in usage error would not be reported for the subclass.
The problem was that the extractClassFromArgument function couldn't get
the class type from Java code. It was looking for a ConeClassLikeType,
but found a ConeFlexibleType instead.
