QQuickRectangle: Optimize setGradient
Similarly to the QQuickPen optimization, we can avoid a signal
connection by using the parent pointer of the QQuickGradient.
This improves qmlbench's delegates_rect_gradient.qml by ~6% for me:
Before: 300.6 frames; using samples; MedianAll=301; StdDev=4.61519, CoV=0.01535
After: 320.4 frames; using samples; MedianAll=321; StdDev=1.94936, CoV=0.00608414
Again, hopefully, the resulting lessening in allocations and improvement
in performance will help stabilize the benchmark a little on some
systems, as well as the improvement to performance and memory use.
