Create a virtual test suite for layout test under fast/events/touch

The feature PaintTouchActionRects could introduce different behavior
than today's code of computing the touch action rects. In order to
prevent regression, this CL creates a new test suite for the tests
under fast/events/touch/. The virtual suite run those tests with
--enable-blink-features=PaintTouchActionRects.
