 * Replace filesystem::directory_iterator
 * Replace filesystem::filesystem_error exception
 * Replace filesystem::temp_directory_path
 * Replace filesystem::unique path
 * Replace filesystem::ofstream with std::ofstream
 * Replace filesystem::remove
 * Replace filesystem::is_regular_file
 * Replace boost::optional with armnn::Optional in touched files
 * Remove some superfluous includes
