[clang-tidy] Add a checker that removes deducible arguments from std::make_pair
Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.
