Remove Q_DUMMY_COMPARISON_OPERATOR
It's not needed for any of our supported compilers and isn't used in
Qt codbase anymore. It was only required for IBM xlC compiler, which
doesn't seem to support C++17 at the moment (when it does, hopefully
they will also fix the issue).
[ChangeLog][QtGlobal] Removed the Q_DUMMY_COMPARISON_OPERATOR macro,
which was needed to workaround outdated template instantiation rules
on some outdated compilers.
Fixes: QTBUG-105098
