Add Windows compilation target

Previously, the ci steps were skipped for the Windows compilation
target. This new approach runs the ci steps on a Windows machine.
This is suboptimal for multiple reasons:
* the `ci` script does not work on a machine. Thus, calls to the script
  are removed by this change.
* our local workflow involves cross-compilation, and thus it is
  slightly different from github workflow
* the release builds are currently built via cross-compilation
The reason we can't use `ubuntu-latest` as a build machine is that the
`cargo test` requires an interpreter for a `.exe` file.
