Ensure AnimatedImage currentFrame/onCurrentFrameChanged 2.0 compatibility
Change 5d995ae122aa07486ead849560b74d2b62b883bb did not make the actual
QQuickImageBase::currentFrameChanged signal accessible to the Qt Quick
2.0 revision. Normally the QML engine would implement a JS
onCurrentFrameChanged handler by connecting to the currentFrame
property's frameChanged notifier signal; but in this case it tried to
connect to the explicit QQuickImageBase::currentFrameChanged signal
instead (because the name is a better match), and failed because of the
revision. So we need another duplicate unrevisioned signal
QQuickAnimatedImage::currentFrameChanged for use when the import is less
than Qt Quick 2.14.
As pointed out during review, an autotest for the revisioning is good to
have anyway.
Fixes: QTBUG-78713
