Similarly, `defaultedSpecialMemberIsConstexpr` should almost always return true in c++23 ( per https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2448r2.html#pnum_34 and https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2448r2.html#pnum_33 ) and `CheckExplicitlyDefaultedComparison` should alwways set the constexpr flag in c++23 mode per https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2448r2.html#pnum_39
