Fortran: Add support for free- and fixed-form flags

Define a "Fortran_FORMAT" target and source file property.  Initialize
the target property from a "CMAKE_Fortran_FORMAT" variable.  Interpret
values "FIXED" and "FREE" to indicate the source file format.  Append
corresponding flags to the compiler command line.
