Fortran: Support compilers using no module prefix on submodule files

Define `CMAKE_Fortran_SUBMODULE_SEP` with an empty string to mean that
the compiler uses no module prefix on its submodule files.

Also add a default fallback to use the `.mod` extension when
`CMAKE_Fortran_SUBMODULE_EXT` is not set.  This is a better guess than
no extension at all.
