Daniel Rakos 6df53e0401 MeshLibrary export improvements
- From now materials assigned to the MeshInstance (not the Mesh) get exported
  into the MeshLibrary when such materials exist. This enables workflows where
  the MeshLibrary is exported from an imported scene (e.g. GLTF) where the
  materials assigned to the Mesh (not the MeshInstance) get overwritten on
  re-import, thus can't use editor set materials in the exported MeshLibrary
  unless they are assigned to the MeshInstance whose materials get saved with
  the inherited scene thus persist across re-imports.
- When appending to an existing MeshLibrary only generate previews for newly
  added or modified meshes.
- During preview generation transform camera and lights instead of the mesh
  and use the source MeshInstance's transform for the mesh to avoid weird
  previews being generated for meshes with a position dependent material
  (e.g. when using triplanar mapping).
- Adjust the camera angle and light directions used in mesh preview generation
  for better results.
