Add functional Graphics View benchmarks.

Widgets and use cases are externally developed and imported from:
git://gitorious.org/+qt-performance-test-developers/qt/qt-performance-test-developers-clone.git
(master branch, tests/benchmarks/uimodels/GraphicsViewBenchmark)

I couldn't simply import everything because the benchmarks were heavily
dependent on an internal measuring tool involving QtScripts and whatnot,
not suitable for inclusion in the Qt repository. Everything is now converted
into proper QTestLib compatible benchmark functions.
