We can't use qt_scoped_lock/qt_unique_lock here, so port to
std::unique_lock and std::lock_guard for now.
This is in preparation of deprecating QMutexLocker in favor
of std::unique_lock and std::scoped_lock.
In QFutureInterface, change the return type of mutex() from
QMutex* to QMutex&, so we don't need to deref when passing
to std::lock_guard. We need to keep the old method around
for BC reasons, so the new one needs an artificial function
argument for disambiguation. This will vanish come Qt 6.

Finally, fix the backbuffer handling. What we originally

DXGI used to work with D3D11 and earlier. GetBuffer() can
only be used to query index 0, and that's the backbuffer,
the rest is managed internally. Follow this model.

Qt Quick apps feature an occasional flicker which seems to be caused
by updating the contents of a Static (or Immutable) QRhiBuffer in a frame
where the QRhiBuffer in question is read in the previous frame as well.
On macOS these types map to a Managed MTLBuffer and only one native buffer
object (MTLBuffer). It seems modifying such a buffer is not safe if the
previous frame has not completed. (this may be as expected, but hard to
tell due to Metal's underdocumented automatic hazard tracking which we
rely on atm)
So for now switch to having 2 native buffers, like we do for Dynamic
(on iOS/tvOS this would be the case anyway since there all buffers are
host visible and slotted regardless of the QRhiBuffer type).
This seems to solve the issue.
To be seen if we want to move to a more Vulkan-like setup where Immutable
and Static map to device local (Private).
