cmVisualStudio10TargetGenerator: Prepare to handle C# projects

Generalize some internal infrastructure to prepare for generating
either `.vcxproj` or `.csproj` files.

- Add member string for project file extension
- Add member enum for project type
- Add member flag for in-source build
- Add member flag for managed build
- Rename PathToVcxproj to PathToProjectFile
