Brad King d80ecba5c2 Fortran: Fix submodule file names across compilers
The naming convention for submodule files varies across compilers.  Add
a table to the compiler information modules and thread the information
through to the Fortran module dependency parser.  Fill out the table for
compiler ids known to support Fortran submodules.

Fixes: #18746
