gdb/fortran: Add type info of formal parameter for clang.

Additional compiler generated formal parameter exist with clang and type
information for the same is added accordingly. Also few kind parameter
printing are removed which is not default for clang.
Note: More details about this kind parameter omission while printing can
be found with similar patch
