std::expected<T,E>::~expected

Main template destructor

Destroys the contained value:

• If has_value() is true, destroys the expected value.
• Otherwise, destroys the unexpected value.

This destructor is trivial if std::is_trivially_destructible_v<T> and std::is_trivially_destructible_v<E> are both true

void partial specialization destructor

If has_value() is false, destroys the unexpected value.

This destructor is trivial if std::is_trivially_destructible_v<E> is true
