[libc++] Optimize ranges::copy_backward for vector<bool>::iterator (#121026) ...

As a follow-up to #121013 (which focused on `std::ranges::copy`), this
PR optimizes the performance of `std::ranges::copy_backward` for
`vector<bool>::iterator`, addressing a subtask outlined in issue #64038.
The optimizations yield performance improvements of up to 2000x for
aligned copies and 60x for unaligned copies.
