Enable clang-tidy modernize-replace-disallow-copy-and-assign-macro

Official docs:

  Finds macro expansions of DISALLOW_COPY_AND_ASSIGN(Type) and replaces
  them with a deleted copy constructor and a deleted assignment
  operator. Before the delete keyword was introduced in C++11 it was
  common practice to declare a copy constructor and an assignment
  operator as private members. This effectively makes them unusable to
  the public API of a class. With the advent of the delete keyword in
  C++11 we can abandon the private access of the copy constructor and
  the assignment operator and delete the methods entirely.
