[libc++] Optimize ranges::equal for vector<bool>::iterator (#121084)
This PR optimizes the performance of `std::ranges::equal` for
`vector<bool>::iterator`, addressing a subtask outlined in issue #64038.
The optimizations yield performance improvements of up to 188x for
aligned equality comparison and 82x for unaligned equality
comparison. Moreover, comprehensive tests covering up to 4 storage words
(256 bytes) with odd and even bit sizes are provided, which validate the
proposed optimizations in this patch.
