Compares two paths lexicographically.
1) Checks whether lhs and rhs are equal. Equivalent to !(lhs < rhs) && !(rhs < lhs).
2) Checks whether lhs and rhs are not equal. Equivalent to !(lhs == rhs).
3) Checks whether lhs is less than rhs. Equivalent to lhs.compare(rhs) < 0.
4) Checks whether lhs is less than or equal to rhs. Equivalent to !(rhs < lhs).
5) Checks whether lhs is greater than rhs. Equivalent to rhs < lhs.
6) Checks whether lhs is greater than or equal to rhs. Equivalent to !(lhs < rhs).
7) Obtains the three-way comparison result of lhs and rhs. Equivalent to lhs.compare(rhs) <=> 0.
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::filesystem::path is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.
