The "a"/"*" specifier of the `mrb_get_args()` function will now return `const mrb_value *`. This is because it is difficult for the caller to check if it is an array object and write-barrier if necessary. And it requires calling `mrb_ary_modify()` on the unmodified array object, which is also difficult (this is similar to #5087).
