[libc++] Fix {std, ranges}::equal for vector<bool> with small storage types (#130394)

The current implementation of `{std, ranges}::equal` fails to correctly
compare `vector<bool>`s when the underlying storage type is smaller than
`int` (e.g., `unsigned char`, `unsigned short`, `uint8_t` and
`uint16_t`). See [demo](https://godbolt.org/z/j4s87s6b3)). The problem
arises due to integral promotions on the intermediate bitwise
operations, leading to incorrect final equality comparison results. This
patch fixes the issue by ensuring that `{std, ranges}::equal` operate
properly for both aligned and unaligned bits.

Fixes #126369.
