Replace which_dotnet_version with a simple function that converts the
value of MSVC_VER to its corresponding enum value in the VS project
generator.
This reduces the maintenance burden when adding support for a new VS
version, because we do not need to update the registry keys in
which_dotnet_version anymore.
The which_dotnet_version function implemented the following logic:
- find all installed VS versions via registry
- select the "best matching one"
- if there is no best match, select the VS that's in PATH
- create a project for that VS installation
The usefulness of this whole stunt is questionable as the VS version of
Qt's mkspec must match the version of a project using that Qt anyway.
