Instead of storing a string with the signature, write the name, return type and
parameter types separately, reusing the name table. Refactor the name table to
allow it to store not only names of Kotlin entities, but also arbitrary names
and fq-names
Make 'Callable' message of descriptors.proto extensible, extend it in
java_descriptors.proto with a JVM signature of the member. This is needed in
order for annotation deserializer to find out which member in the compiled
bytecode corresponds to which descriptor in the hierarchy.
Create a new module 'serialization.java' containing everything related to
Java-specific serialization of descriptors.
Add an extension point to DescriptorSerializer, allowing to perform
platform-specific serialization on a callable
