[SPEC2DEF] Use explicit ordinals on MSVC, too

This prevents MSVC from reordering the exports in a way that doesn't match our spec file. Also improve the algorithm to apply ordinals, by starting with the first specified ordinal, possibly reserving ordinals for anything declared without an ordinal before.
