Support USD files as 3D scenes in Peek

[FrancoisGrosbellet]

Description of the new feature / enhancement

USD files would be viewed as 3D scenes instead of text files when previewed with Peek.

In a similar fashion to the macOS USD preview, basic 3d controls would available: zooming, panning, and rotating the camera.

Scenario when this would be used?

This feature is strongly relevant for developers and artists working on a USD pipelines, where USD files needs to be opened quickly on a regular basis.
