Use triple fingers to pan the editor on Android

[QbieShay]

Describe the project you are working on

Using Godot editor on Android

Describe the problem or limitation you are having in your project

Currently, Godot 4 uses single finger drag to pan in 2D, which conflicts with dragging around nodes in the system.In many touch devices, pan is done with triple finger. i think the editor should do the same. Perhaps related to #4340 and godotengine/godot#72385

Describe the feature / enhancement and how it helps to overcome the problem or limitation

see above

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

see above

If this enhancement will not be used often, can it be worked around with a few lines of script?

no it's the editor

Is there a reason why this should be core and not an add-on in the asset library?

see above

This was an issue that's being addressed by godotengine/godot#75113.
Panning the editor can also be done using two fingers.
