[gtest] Drop custom-rolled heterogeneous comparator functors in favor of C++ standard ones
* Standard heterogeneous comparator functors such as `std::equal_to<>` and `std::less<>` [have been available since C++14](https://en.cppreference.com/w/cpp/utility/functional/less_void)
* Now that [C++14 is the minimum supported version of C++ in Googletest](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md), let's delete these duplications of the standard library
