Makes sense to collect the stuff in a similarly-named header, and it's
not like any of the QTypeTraits stuff was needed for QTypeInfo.
Makes #include <qtypeinfo.h> _much_ lighter again, at the expense of
qminmax.h now getting <variant>, <tuple> and <optional> instead, but
qminmax.h is much easier to avoid in Qt headers (just use the std
versions) than qtypeinfo.h.
[ChangeLog][QtCore][Potentially Source-Incompatible Changes] The
qtypeinfo.h header no longer transitively includes <optional>, <tuple>
and <variant>.
