libstdc++: Fix some -Wsystem-headers warnings
* include/bits/alloc_traits.h (allocator_traits::construct)
(allocator_traits::destroy, allocator_traits::max_size): Add unused
attributes to parameters that are not used in C++20.
* include/std/bit (__ceil2): Add braces around assertion to avoid
-Wmissing-braces warning.
