[Linux] Trackpad Gestures Pinch and Pan broken in 2D and 3D workspace (everything just Zooms)

[leogott]

Godot version

4.0 rc2 (and 3.5.1)

System information

Fedora 36 on a thinkpad with Trackpad

Issue description

Now I'm not entirely sure if this is even implemented, but the changelog for RC2 contained the line

Editor: Fix panning via InputEventPanGesture (notably for macOS) (GH-72884).

and it appears as the Trackpad is supposed to be able to pan and Tilt like in Blender. (It doesn't)

Mayhaps Related: #72414

Steps to reproduce

Click in the 3D Workspace, put two Fingers on the Trackpad and move them sideways

2 Finger Gesture	Expected	Actual
Slide horizontally	Pan	nothing
Slide vertically	Tilt	Zoom
Pinch	Zoom	nothing
Rotate	nothing	nothing

And for the 2D Workspace

2 Finger Gesture	Expected	Actual
Slide horizontally	Scroll left/right	Zoom and erratically Scroll left/right
Slide vertically	Scroll up/down	Zoom and erratic Scroll up/down
Pinch	Zoom	nothing
Rotate	nothing	nothing

The erratic Scrolling in the 2D workspace can't be observed in the RC1 build or a 3.5.1 build,
and seems to be more likely when several gestures are combined and done quickly.

Now I'm not entirely sure if this is even implemented, but the changelog for RC2 contained the line

InputEventPanGesture and InputEventMagnifyGesture are supported only on macOS and Android.

• Duplicate of Implement InputEventGesture (incl. Pan and Magnify) for all platforms #13139.

The 2D editor issue is most likely due to #77212.
