[libc++] Fix ambiguous call in {ranges, std}::count (#122529)
This PR fixes an ambiguous call encountered while using the
`std::ranges::count` and `std::count` algorithms with `vector<bool>`
with small `size_type`s.
The ambiguity arises from integral promotions during the internal
bitwise arithmetic of the `count` algorithms for small integral types.
This results in multiple viable candidates:
`__libcpp_popcount(unsigned)`,` __libcpp_popcount(unsigned long)`, and
`__libcpp_popcount(unsigned long long)`, leading to an ambiguous call
error. To resolve this ambiguity, we introduce a dispatcher function,
`__popcount`, which directs calls to the appropriate overloads of
`__libcpp_popcount`. This closes #122528.
