If neither <filesystem> nor <experimental/filesystem> is detected, then require <boost/filesystem.hpp>. If user defines BOOST_GIL_IO_USE_BOOST_FILESYSTEM macro, then <boost/filesystem.hpp> is pre-selected and required, and search for any of the C++ standard implementation is skipped. Remove end-user macro BOOST_GIL_IO_ADD_FS_PATH_SUPPORT Require tests to always build with support of either detected C++ filesystem or pre-selected Boost.Filesystem. Closes ##222
