JVM IR: copy corresponding property+annotations for DefaultImpls methods

Instead of using methodSignatureMapper which was an obsolete hack to
make accessor names "getFoo" instead of "<get-foo>".

In particular, this keeps the `@Deprecated` annotation on the
corresponding property, which results in ACC_DEPRECATED in codegen.
