Allow a GeneratorFactory handling of more than one generator

Pass the name of the requested generator to the generator factory,
which is now responsible to check if it can create a matching
generator for the name. This allows us to add more logic to the
factory in a next step, so that not every possible generator needs
to get registered explicit in cmake::AddDefaultGenerators().
