Fix mocking method arguments with templated copy constructors.

A previous change removed workarounds for old compilers from googletest and googlemock. Unfortunately, a bit of code that started as a workaround for Symbian's C++ compiler is still needed to avoid copy/move constructor ambiguity when mocking functions with certain argument types.

The test case added by this CL is extracted from Chrome's codebase, and was discovered while attempting to roll googletest.

Refactor the `Invoke` and `InvokeWithoutArgs` actions:
 - Replace pump'd classes and functions with templates.
 - Make the polymorphic actions be polymorphic functors instead.
 - Fix Invoke(Callback*) to work with subclasses of the callbacks, instead of trying to diagnose that in gmock_doctor.

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).
