[libc++] Remove unnecessary division and modulo operations in bitset (#121312)
The PR removes the unnecessary division and modulo operations in the
one-word specialization `__bitset<1, _Size>`. The reason is that for the
one-word specialization, we have `__pos < __bits_per_word` (as
`__bitset<1, _Size>` is an implementation detail only used by the public
`bitset`). So `__pos / __bits_per_word == 0` and `__pos / __pos %
__bits_per_word == __pos`.
