Incorporate QQuickDialog::result from QQuickPlatformDialog

The experimental QQuickPlatformDialog in Qt.labs.platform had a bit
more elaborate accepted vs. rejected dialog result handling. Copy the
same logic to QQuickDialog in QtQuick.Controls.

[ChangeLog][Controls][Dialog] Added "result" property that holds
whether the dialog was previously accepted or rejected.
