  [libc++] Test suite portability improvements (#98527)

This patch contains a number of small portability improvements for the
test suite, making it easier to run the test suite with other standard
library implementations.

- Guard checks for _LIBCPP_HARDENING_MODE to avoid -Wundef
- Avoid defining _LIBCPP_HARDENING_MODE even when no hardening mode is
  specified -- we should use the default mode of the library in that case.
- Add missing includes and qualify a few function calls.
- Avoid opening namespace std to forward declare stdlib containers. The
  test suite should represent user code, and user code isn't allowed to do
  that.
