Fix pinch zoom and enable it for TouchpadMagnify events (#30459)

Browse source 
Pinch zoom was broken because pinch zoom events were triggered at -1, -1
in the compositor. This change:

1. Differentiates between magnify and scroll events in the compositor to
   remove the question of where to trigger them.
2. Converts winit TouchpadMagnify events into pinch zoom events so that
   this works properly on MacOS.
