Investigate `raw-dylib` support/workarounds for `unicows`

raw-dylib causes rust to generate import libraries which are, for dependencies, added to their rlib archives. This means they are always linked *before* `unicows.lib`, preventing unicows from replacing calls to `W` Unicode APIs to `A` APIs on 9x/ME.

I'm not sure there is a sensible way of using both at the moment 🤔
