Fix pinch zoom tests on Mac

These tests:
virtual/threaded/fast/events/pinch/pinch-zoom-into-center.html
virtual/threaded/fast/events/pinch/pinch-zoom-pan-position-fixed.html
pinch-zoom-pan-within-zoomed-viewport.html

were breaking because Mac doesn't support touch events and the pinch
was being done using touch. I've changed to use a touchpad source as
this doesn't affect the meaning of the tests as well as some minor
cleanups.

While here, I also rewrote a number of tests to use gesture-util.js and
the async/await style which is more readable and easier to produce
non-flaky tests.
