clang-tidy: Enable cppcoreguidelines-explicit-virtual-functions

Adds override (introduced in C++11) to overridden virtual functions
and removes virtual from those functions as it is not required.

virtual on non base class implementations was used to help indicate
to the user that a function was virtual. C++ compilers did not use
the presence of this to signify an overridden function.

In C++11 override and final keywords were introduced to allow
overridden functions to be marked appropriately. Their presence
allows compilers to verify that an overridden function correctly
overrides a base class implementation.

This can be useful as compilers can generate a compile time error
when:
- The base class implementation function signature changes.
- The user has not created the override with the correct signature.
