[libc++] Fix improper static_cast in std::deque and __split_buffer (#119106)

This PR addresses the improper use of `static_cast` to `size_t` where
`size_type` is intended. Although the `size_type` member type of STL
containers is usually a synonym of `std::size_t`, there is no guarantee
that they are always equivalent. The C++ standard does not mandate this
equivalence.

In libc++'s implementations of `std::deque`, `std::vector`, and
`__split_buffer`, the `size_type` member type is defined as
`std::allocator_traits<allocator_type>::size_type`, which is either
`allocator_type::size_type` if available or
`std::make_unsigned<difference_type>::type`. While it is true for
`std::allocator` that the `size_type` member type is `std::size_t`, for
user-defined allocator types, they may mismatch. This justifies the need
to replace `static_cast<size_t>` with `static_cast<size_type>` in this
PR.
