Raycast3D is very hard to see in editor

[QbieShay]

Godot version: v3.1 c861756

Issue description:
Raycast3D gizmo is almos impossible to view if it overlaps with the axis. It also z-fights with the axis.
My proposal is to have a more visible gizmo for the raycast node.

What would be the best way to approach this?

@MCrafterzz Displaying RayCast3D as a thin rectangle box instead of a line would likely solve this.

[QbieShay]

I'd probably recommend an arrow shape, similar to the one used for directional lights, but thinner (and that represents the ray, so the length of the "body" of the arrow shall vary depending on the length of the ray casted).

Can I take this up, since it looks like it's not fixed yet? I'll start working on this from next week though due to exams (so if anyone else wants it and is able to take it instead, please let me know)

[Calinou]

@lightspot21 Sure 🙂

Feel free to salvage things from #33103.

[MarcusElg]

There's not much to salvage but sure 😉

This was fixed by #46529 in master and backported to 3.4 by #49726, closing.
