Extract move assign / construction functionality in SkeletonBase into separate class

[LittleHuba]

What

SkeletonBase currently has a Cleanup method which is called both in the destructor and the move assignment operator. We should try to extract the functionality needed in the move constructor / assignment operator to a separate class so that SkeletonBase can have a default move constructor / move assignment operator if possible.

How

@LittleHuba Maybe I'm looking into the wrong branch, but here: https://github.com/eclipse-score/communication/blob/main/score/mw/com/impl/skeleton_base.h the SkeletonBase does not have a explicitly defined move-assignment operator.

My mistake, the move assignment operator is in the protected section. Thanks @crimson11 for pointing that out.
