build: link swiftCore against Shell32
build: link swiftCore against Shell32

We are now using Shell APIs for the command line parsing.  Ensure that we link
against the Shell32 library.  This is needed for the cross-compilation as on
Windows, the environment will set a default link against a number of libraries.
This is more precise and explicit.
