remove GTEST_ARRAY_SIZE_

Browse Source 
This macro didn't work when an array was passed to a function by pointer,
in which case the information about its size was lost.
Better alternatives are:
* std::extent<T>::value (compile-time)
* std::array<T, N>::size() (compile-time)
* std::distance(std::begin(array), std::end(array)) (run-time)
