Extension spec: https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_unlit
The extension can not be correctly represented with a UsdPreviewSurface, but we might be able to emulate it using the emissive color.
In MaterialX, this feature should be covered by the recently introduced 'unlit' shader node: AcademySoftwareFoundation/MaterialX#860

Implemented in branch, needs testing and dedicated test.
