VS: Fix Fortran target type selection with RC sources
The Intel Fortran .vfproj
files do support both Fortran and the
Windows Resource compiler (.rc)
files. Prior to CMake 3.9 we did not
support that, but !643 (merged) accidentally enabled it.
It was then broken by !2913 (merged).
Restore support for Fortran+RC in VS projects and add a test case.
Fixes: #19002 (closed)
