Make QFutureWatcher::isFinished() consistent with the watched QFuture

All the getters of QFutureWatcher are consistent with the getters of the
corresponding QFuture, except for the isFinished() method, which returns
'true' only after the finished() signal is delivered. This behavior
might be unintuitive for the users. In particular, isFinished() returns
'false', even if it's called immediately after waitForFinished().

[ChangeLog][QtCore][QFutureWatcher][Important Behavior Changes] The
QFutureWatcher::isFinished() method now indicates if the related
QFuture is finished, instead of indicating if the finished() signal was
delivered. This makes it consistent with the future that is being
watched.

Fixes: QTBUG-91048
Pick-to: 6.1 6.2
