[libc++] Re-document how to use <filesystem> with various versions of libc++ 

This documentation was removed when we added <filesystem> to the dylib

will have an easier time migrating.

$ export LD_LIBRARY_PATH=<libcxx-install-prefix>/lib

Using ``<filesystem>``
======================
Prior to LLVM 9.0, libc++ provides the implementation of the filesystem library
in a separate static library. Users of ``<filesystem>`` and ``<experimental/filesystem>``
are required to link ``-lc++fs``. Prior to libc++ 7.0, users of
``<experimental/filesystem>`` were required to link libc++experimental.
Starting with LLVM 9.0, support for ``<filesystem>`` is provided in the main
library and nothing special is required to use ``<filesystem>``.
Using libc++experimental and ``<experimental/...>``
