Compares two views.
All comparisons are done via the compare() member function (which itself is defined in terms of Traits::compare()):
-  Two views are equal if both the size of lhsandrhsare equal and each character inlhshas an equivalent character inrhsat the same position.
- The ordering comparisons are done lexicographically -- the comparison is performed by a function equivalent to std::lexicographical_compare.
The implementation shall provide sufficient additional constexpr and noexcept overloads of these functions so that a basic_string_view<CharT,Traits> object sv may be compared to another object t with an implicit conversion to basic_string_view<CharT,Traits>, with semantics identical to comparing sv and basic_string_view<CharT,Traits>(t).
