Add CI workflows for building and validating driver samples (#775)

* Add scripts to build a set of samples, as well as individual solution folders.
* Add GitHub workflows to use these scripts and build all samples on push and changed samples on pull request.

For now samples will be built under Windows 2019 but eventually workflow will be moved to run under Windows 2022.
