Prevent accidental copies of expensive-to-copy object types

[vuule]

Description

Deleted copy constructor of classes that are expensive to copy. Some of these classes have const data members, so they previously had the move constructors implicitly deleted, making accidental copies even more likely.
Also made the non-default move constructors noexcept to avoid implicit copies in container like std::vector.

Seems fine to me. How did you decide which of the move constructors to make noexcept? Should we be more aggressive in making more of those move constructors noexcept?

Defaulted move constructor don't need the keyword, since the noexcept-ness is automatically determined based on the data members (which do have noexpect move ctors). So, we only need explicit noexcept for the custom move ctors, of which there are very few and should be covered in this PR.
