AnimatedImage already had these properties, but some typically non-animated
image formats such as PDF, TIFF and ICO can also support multiple pages.
In either case, the currentFrame property can be used to select a specific
frame or page. However an AnimatedImage uses a QMovie to do that, whereas
a plain Image uses QQuickPixmap. So the accessors need to be virtual in
order to have these different implementations.
[ChangeLog][QtQuick][Image] Image and BorderImage now have currentFrame
and frameCount properties which can be used to step through the frames of
multi-page image formats such as TIFF, WEBP and ICO.
