  Log Message:
  -----------
  [libc++] Improve test coverage for copy/move ctors for vector<bool> (#120132)

The current tests for `vector<bool>` fail to adequately cover realistic
scenarios, as they are limited to cases of up to 3 bytes, representing
less than 1/2 of a word size on a 64-bit system. However, most
`vector<bool>` operations rely on code paths triggered only when
handling multiple storage words (8 bytes each). To address this gap,
this PR rewrites the tests for copy and move constructors, as well as
allocator-extended copy and move constructors, ensuring that previously
untested code paths are now thoroughly validated.
