Deprecate the pause-related APIs of QFuture* classes

Deprecated the pause-related APIs of QFuture* classes and
added alternatives having "suspend" in the name instead.

With 2f15927f01ceef0aca490746302a5ea57ea9441c new
isSuspended()/suspended() APIs have been added to QFuture* classes for
checking if pause/suspension is still in progress or it already took
effect. To keep the naming more consistent, renamed:

 - setPaused() -> setSuspended()
 - pause() -> suspend()
 - togglePaused() -> toggleSuspended()
 - QFutureWatcher::paused() -> QFutureWatcher::suspending()

Note that QFuture*::isPaused() now corresponds to (isSuspending() ||
isSuspended()).

[ChangeLog][Deprecation Notice] Deprecated pause-related APIs of
QFuture and QFutureWatcher. Added alternatives having "suspend" in
the name instead.
