Subject: Flickable: add a trackpad (touchpad) autotest

We've had this feature for a long time, to use pixel deltas and scroll
phase effectively, but no autotest until now.  It's still not very
thorough but it's a start.

Task-number: QTBUG-55871
Change-Id: Iaf6e7a842ce90828da3253e8673cac9905abd046
