v3.2.1 stable edition

Windows 10

Issue description:

Using load(path) on a file outside of the res:// results in a "Loader not found error" despite the file existing

I'm working on a project that takes 3D models (.obj) from anywhere in a user's computer and adds them to the scene. I was able to find a workaround for 2D files (.png) using the Image class, but I couldn't find an equivalent for 3D. Mainly the Image.load(path) and the ImageTexture.create_from_image(Image) have no counterparts for Meshes.

Steps to reproduce:
use the load(path) method on a path outside of res://

Minimal reproduction project:

Godot load issue demo.zip
This project has a DNA.obj file that can be loaded when it's in the res:// folder, if you make a copy on the desktop and attempt to reach it the error is repeated

#14879 deals with the same issue, there doesn't seem to be a fix for it yet, only workarounds for some image and audio files.
