    Bind(C): Fix type encodings in ISO_Fortran_binding.h

    ISO_Fortran_binding.h had many incorrect hardwired kind encodings in
    the definitions of the CFI_type_* macros.  Additionally, not all
    targets support all the defined type encodings, and the Fortran
    standard requires those macros to have a negative value.

    This patch changes ISO_Fortran_binding.h to use sizeof instead of
    hard-coded sizes, and assembles it from fragments that reflect the
    set of types supported by the target.
