gdb/fortran: Introduce fortran-operator.def file
Future commits will add more Fortran specific expression operators. In preparation for these new operators, this commit adds a new fortran-operator.def file similar to how GDB already has ada-operator.def. I've moved UNOP_KIND the Fortran specific operator I introduced in commit 4d00f5d8f6c4 into this file, and renamed it to make it clearer that the operator is Fortran specific. I've then updated the Fortran exp_descriptor table (exp_descriptor_f) to use entirely Fortran specific functions that now handle UNOP_FORTRAN_KIND (the new name for UNOP_KIND). There should be no visible changes for standard users after this commit, though for developers, the output when 'set debug expression 1' is now better, before: (gdb) p kind (l1) Dump of expression @ 0x2ccc7a0, before conversion to prefix form: Language fortran, 5 elements, 16 bytes each.
