  -----------
  [libc++] Add missing conditionals for feature-test macros (#80168)

We noticed that some feature-test macros were not conditional on
configuration flags like _LIBCPP_HAS_NO_FILESYSTEM. As a result, code
attempting to use FTMs would not work as intended.

This patch adds conditionals for a few feature-test macros, but more
issues may exist.
