general: Move deleted copy/move constructor/assignment operators to public interface

This allows for better compiler errors, where the compiler will state a
copy or move couldn't occur due to the relevant function being deleted.

Previously a compiler would warn about the relevant function not being
accessible (which, while true, isn't as informative as it could be).
