    Fortran: fix treatment of character, value, optional dummy arguments
[PR107444]

    Fix handling of character dummy arguments that have the optional+value
    attribute.  Change name of internal symbols that carry the hidden presence
    status of optional arguments to distinguish them from the internal hidden
    character length.  Update documentation to clarify the gfortran ABI.

    gcc/fortran/ChangeLog:

            PR fortran/107444
            * trans-decl.cc (create_function_arglist): Extend presence status
            to all intrinsic types, and change prefix of internal symbol to
'.'.
            * trans-expr.cc (gfc_conv_expr_present): Align to changes in
            create_function_arglist.
            (gfc_conv_procedure_call): Fix generation of procedure arguments
for
            the case of character dummy arguments with optional+value
attribute.
            * trans-types.cc (gfc_get_function_type): Synchronize with changes
            to create_function_arglist.
            * doc/gfortran/naming-and-argument-passing-conventions.rst: Clarify
            the gfortran argument passing conventions with regard to OPTIONAL
            dummy arguments of intrinsic type.

    gcc/testsuite/ChangeLog:
