MacBook trackpad panning and orbit are slow in 3D viewport

[CaptainKraft]

Godot version

4.0.2.stable

System information

M1 MacBook Pro 2021, Ventura 13.3.1

Issue description

Panning and orbiting in the 3D viewport with the trackpad on my MacBook Pro are very slow. Increasing "Orbit Sensitivity" in the editor settings to 2.0 (the maximum) helps a bit, but then when I go back to using a mouse, the sensitivity is extremely high.

I checked issue #72242, which was resolved, but it seems like those changes only affected the 2D viewport behavior.

Here is a video of the behavior I'm seeing:

Steps to reproduce

1. Open the 3D view of any project
2. Using two-finger scrolling on a MacBook Pro trackpad, orbit around the viewport
3. Alternatively, hold the panning modifier when moving to test panning

Minimal reproduction project

This can be reproduced with a new empty project.

As a temporary workaround for the slow orbiting, you might benefit from increasing your trackpad scroll speed in system settings. As for panning, there is no sensitivity option, so it might be worth to add a "Translation sensitivity" slider, something like: (Can also increase the orbit sensitivity maximum for cases like these)

@geminax Thanks! Your translation_sensitivity addition was the missing piece I needed to align my Godot experience with years of Unity/Maya muscle memory. Hopefully it helps with OP's original issue as well.

Should we get this PR started (if you haven't already)?

Update: Hope you won't mind, I just prepared a PR based on your code. #81714
