Fixed a bug in the vertex order for restricted Catmark vertex-vertex kernel batches.
Fixed omissions in `osd/mesh.h`.

* added `OsdMeshInterface::GetFarMesh` and `OsdMesh::GetFarMesh` to match `OsdGLMesh` and `OsdD3D11Mesh`
* added `interleaved` argument to `OsdMesh::Refine` to match `OsdMeshInterface::Refine`
