Richard Levitte d32d304836 Fix ossl_param_bld_push_{utf8,octet}_string() / param_bld_convert()
ossl_param_bld_push_{utf8,octet}_string() saved the constant string
pointer to a non-constant structure field, so we change that field to
a pointer to a constant.  We also modify param_bld_convert() to
pretend the resulting pointer for PTR types points to a constant as
well.

Completes #9649
