  [UI side compositing] Fix swipe tests to work with UI-side compositing

Reviewed by Tim Horton.

Swipe tests need to wait for the UI process to receive a layer tree commit with the up-to-date
event regions before starting a swipe, so `await UIHelper.ensurePresentationUpdate()` before
swiping.

`swipe-back-with-passive-wheel-listener.html` needs to use the "slow swipe" function that
allows for processing between events, so that the UI process gets a response from the
web process to allow the swipe to start.
