Fix warning about deprecation of implicit operations such as copy constructors or assignment operators.

Specifically:

MatcherBase's default copy constructor, assignment operator, move operator, and move assignment operator are now declared explicitly rather than depending on the compiler implicit generation (which is disallowed/warned against due to MatcherBase's declaration of the destructor).
