While at the moment we don't have aliasing support in QSharedPointer,
introduce owner-based comparisons and hashing. This also fulfills some
use cases in lieu of operator== for QWeakPointer (which got deprecated
by bb23a05905).
I'm using C++26/P1901's spelling of owner_equal, instead of
Boost.SmartPtr's spelling (owner_equal*s*). Given the niche use case,
the lack of interoperability with Qt's own containers, as well as the
Standard comparison objects' semantics (std::owner_less,
std::owner_equal), I don't think we should be giving these a Qt-ish name
as it would be pretty useless.
[ChangeLog][QtCore][QSharedPointer] Added owner_before, owner_equal,
owner_hash.
[ChangeLog][QtCore][QWeakPointer] Added owner_before, owner_equal,
owner_hash.
