QQuickImageBase: Avoid a signal connection altogether
7568922fa240e6e9440e9c6e93bf8ec00c06ec17 already made this faster (by making it
not string-based, and used when it was required).
We can do one better after d870ea28656a2155c39a1aabefa1c56871a017e4, by
avoiding the connection altogether, and explicitly only updating when
the DPI changes.
This doesn't affect qmlbench performance a great deal AFAICT (presumably
because ItemSceneChange events don't just fall out of the sky); but it will help
when they do happen, and it will also no longer allocate memory (for the
connection).
