Callum Moffat 9232ccb480 Web trackpad pan (flutter/engine#36346) ...

* Guess at trackpad pans on web

* Add test

* Update comment

* Handle macOS accelerated scroll wheel

* Fix test after last commit

* Disable on firefox

* Pull out _isTrackpadEvent and add doc links

* Fix issue with floating point / integer conversion error.

* Workaround for magic mouse events which happen to be divisible by 120.

* Refactor to handle bad luck in accelerated mouse deltas.

Basically, bias towards choosing mouse, but if timestamps are available,
we can check the previous event and ensure that false-mouses are avoided.

* Use 120 wheelDelta to identify mouse-accelerated events instead of 240

Apparently some high-precision mice use 120 instead of 240 as the
wheelDelta per tick.

* Handle multiple bad-luck events in a row.

Also fix setting of timeStamp in test.

* Cleanup parameters
