win: Don't use rsp files when linking gn either.

The longest link line in gn is < 3000 bytes (gn_lib.lib) and even
if gn_lib was a source set, the link line for gn_unittests.exe
would still be less than 8000 bytes, so we're comfortably below
the limit where rsp files are needed.

While here, change flag order to be more like on linux and mac.

No behavior change.
