refactor: Provide a Virtual Method Anchor for Classes in Headers

Define at least one virtual method in polymorphic class cpp files to
improve link efficiency. Do so by defining a defaulted destructor or
another overridden virtual method in the class cpp file.
Also add explicitly defaulted copy/move constructors and assignment
operators to follow the rule of five and to avoid compiler suppression
of these functions due to the addition of a user-provided destructor.
Where neccessary, create new cpp files and add them to CMakeLists and
Testing.cmake. Set the -Wweak-vtables by default when compiling with
clang to issue warnings for new classes that do not comply with this
pattern.

See http://llvm.org/docs/CodingStandards.html#provide-a-virtual-method-anchor-for-classes-in-headers.

Fixes #6036.
