[libc++][test] Refactor tests for rotate and rotate_copy (#126458)

This PR refactors the tests and fix some problems:  
- Refactor similar tests using `types::for_each` to remove redundant code;
- Explicitly include the missing header `type_algorithms.h` instead of relying
  on a transitive include;
- Fix the incorrect constexpr declaration in `rotate.pass.cpp`, where
  the `test()` function is incorrectly defined as `TEST_CONSTEXPR_CXX17`,
  which is wrong since `std::rotate()` becomes constexpr only since C++20.
