SwiftRemoteMirror: do not mark as weak import on Windows
SwiftRemoteMirror: do not mark as weak import on Windows

Weak import semantics are not available on PE/COFF.  Ensure that we do not mark
the type as having weak import semantics.  Otherwise, the dllimport'ed symbol is
marked as `dso_local` which is invalid.
