[[nodiscard]] bool empty() const noexcept;
Checks if the path in generic format is empty.
true if the path is empty, false otherwise.
An empty path can be obtained by calling clear and by default-constructing a
path. It can also be returned by a path decomposition function (such as extension) if the corresponding component is not present in the path.
An empty path is classified as a relative path.
