At the same time, simplify CMakeLists magic for libraries that want to include Swift code in the library. The Lib-less name of the library is now always the module name for the library with any Swift additions, extensions, etc. All vfs overlays now live in a common location to make finding them easier from CMake functions. A new pattern is needed for the Lib-less modules to re-export their Cxx counterparts.
