cmGeneratorTarget: Adopt Fortran module directory generation

Move code to create/get the fortran module directory from the
cmCommonTargetGenerator to cmGeneratorTarget.

Rename the ComputeFortranModuleDirectory method to
CreateFortranModuleDirectory as this method *creates* the directory if
it is missing.
