Improve testing on Windows (#3142)

This PR contains:
- Changes that enable/disable tests on Windows to allow for better local testing.
- Also changes many abort() into Fatal() when it is really just exiting on error. This is because abort() generates a dialog window on Windows which is not great in automated scripts.
- Improvements to CMake to better work with the project in IDEs (VS).
