Improvement: Add method support to GenericProxy

[crimson11]

What

Goal: score::mw::com::impl::GenericProxy currently only supports Event communication. Since now also Methods are available it shall be extended with GenericProxyMethod support.

How

1. Introduce a GenericProxyMethod. It should be similar to GenericProxyEvent
2. Design/Decide, how the signature of GenericProxyMethod shall look like! I guess - opposed to our existing ProxyMethod template variants, it won't be a class template at all. The signature for call operator should look like this:
   score::Result<MethodReturnTypePtr<void>> operator()(MethodInArgPtr<void>>);
   There we need void-specializations for the pointers above ...

Estimates for realization

Rough estimate: 2 weeks
