QFuture: port from QSharedPointer to std::shared_ptr
Compared to std::shared_ptr, QSharedPointer requires 2x the atomic
operations per copy, and this code uses _a lot_ of copies.
Port to std::shared_ptr. The uses are all in inline, non-exported
code, so there's no BC or SC issue here. Old code will happily
continue to use its QSharedPointer-based code, while recompiled code
will enjoy the transparent efficiency gain.
This also helps prepare QtCore for an eventual QT_NO_SHARED_POINTER
(which QtCore will not be able to set on itself, because QPointer is
still not ported away from QWeakPointer, but which should affect as
few headers as possible).
Pick-to: 6.5
