RuntimeTypeMapper assumed that JavaPropertyDescriptor was necessarily backed by
JavaField, which has changed when we started to load Java method (or a pair of
methods) overriding a Kotlin property as a property, not as a method. Another
example of this situation is special built-in properties which are mapped to
Java methods, e.g. java.util.Collection#size() <-> kotlin.Collection#size. This
change adds support for the case of a property backed by a JavaMethod.
Note that callable references or usage of any reflection API related to
built-in members is not supported anyway and will currently fail with errors
