Cleanup: enable modernize-use-equals-default check

This removes a lot of unnecessary code that is generated by
the compiler automatically.

In very few cases, a defaulted destructor in a .cc file is
still necessary, because of forward declarations in the header.

I removed some defaulted virtual destructors, because they are not
necessary, when the parent class has a virtual destructor already.

Defaulted constructors are only necessary when there is another
constructor, but the class should still be default constructible.
