QQuickImageBase: Minimize the cost for devicePixelRatio setting.
* Don't convert QUrl to QString twice (that massively blows up transient
allocations and is very slow)
* Don't do anything at all if a sourceSize isn't set (checking it is super
cheap)
This fixes the performance regression (introduced in 428b92583ee2102c7ef16776a9b7785df7ff4e2c)
in the delegates_image creation benchmark (from ~520 up to ~540 items per frame).
