VS: Rename VS 15 generator to 'Visual Studio 15 2017'

The final name of this VS version was announced:

 https://blogs.msdn.microsoft.com/visualstudio/2016/11/16/visual-studio-2017-rc/

Add the year to the generator name accordingly.  For convenience, map
the name without the year to the name with the year.
