Replace unicorn bindings with Nuget package (#4378) 
* Replace unicorn bindings with Nuget package

* Use nameof for ValueSource args

* Remove redundant code from test projects

* Fix wrong values for EmuStart()

Add notes to address this later again

* Improve formatting

* Fix formatting/alignment issues
