Allow color specification on `Asset3D`

[EtaLoop]

What

The idea is to reproduce behavior of Mesh3D regarding color modification on Asset3D :

• add albedo_factor
• add vertex_colors as in Mesh3D

In order to overwrite white default texture of Asset3D loaded from stl and obj (gltf already have albedo_factor in file).

See: #5253

let me know when you think this is ready for review again! :) (or use the little "re-request review" button so this shows up in my review queue again)

Now that https://github.com/rerun-io/rerun/pull/7824 is in, it should be a lot more straight forward to do this!

Thanks a lot :+1:

I wanted to push a fix for the doc issues ci brought up, but I don't have permissions it seems (hum, this usually works, no idea why) That's my fix, can you cherrypick it in? https://github.com/rerun-io/rerun/commit/5c7bea0e7b817cd4abdaaebb74005f533920230a

Done, sorry for the mess up there :sweat:
