[BlinkGenPropertyTrees] Add more scrolling tests expectations

Most "scrolling" tests in Blink are in the fast/scrolling and
fast/events directories, the latter due to testing touch, wheel,
keyboard, etc. events. Many of these will use eventSender and so avoid
the composited path entirely so they provide just some mildly useful
main-thread scrolling coverage. Some do use gpuBenchmarking and are thus
more useful.
