Re: [I] [C++] binary_slice with its default `stop` raises "Negative buffer resize" [arrow]

   The overflow is in `SliceBytesTransform::MaxCodeunits` (scalar_string_ascii.cc on main):
   `(opt.stop - opt.start + opt.step - 1) / opt.step` with the default `stop` of
   `numeric_limits<int64_t>::max()` wraps negative when `start > 0`, and that negative bound is what
   becomes "Negative buffer resize". #36575 fixed the same expression for `utf8_slice_codeunits`;
   the byte-slice transform still has the original form.
