Remove obsolete HP aC++ workarounds in googletest

HP aC++ for HP-UX on Itanium (A.06.28) only supported up to C++03 and partial C++11 before HPE placed HP-UX and Itanium into maintenance mode. It was discontinued without ever supporting C++14 or C++17.

As GoogleTest requires C++17, the HP-specific workarounds are obsolete and should be removed.
