tweak(build-tools): required build tools for mono v2 runtime

* Clean up of the C# project generation code (removing duplicate code).
* Dedicated v2 native code generator.
* Native enums now show an obsolete warning for both v1 and v2.
* prebuild_natives.bat function for updating native files.
* prebuild_natives.bat fix where it would only update files the new and old file were the same, not when there were actual changes.
