Mark move ctors/assignments noexcept

This should enable using move semantics where possible e.g. in standard
containers.
According to https://en.cppreference.com/w/cpp/language/move_constructor:

To make strong exception guarantee possible, user-defined move
constructors should not throw exceptions. For example, std::vector
relies on std::move_if_noexcept to choose between move and copy
when the elements need to be relocated.
