Move shared packages to NetworkStack project

Both were already statically linked both in the NetworkStack module and
the framework, so this change only reorganizes the file locations.

It makes more sense to have the library files in the NetworkStack module
folder, as changes to these files will be released with the same cadence
as the module, not the framework.
