Trackpad: removal "Trackpad Natural" preference.
This option only affected the 3d rotation (not even 3d panning) and menu items cycle.
Fix T64917 Apple Magic mouse pan is opposite for view3d.rotate.
Now it will just follow the OS preferences and be consistent across all editors.
With OS defaults (Natural) - content tracks finger movement. Objects rotate in the same direction as the fingers,
which also matches the direction of rotation using the gizmo and the middle mouse button.
