Generate metadata and annotations for hidden constructor

Reflection expects to see a callable method for a hidden constructor,
thus, it should be a synthetic accessor.
JVM method signature in metadata should point to the synthetic accessor.
Annotations for hidden constructor should be written on the synthetic
accessor.
