Merge Vertex Indices in USD.

[mikedatsik]

Describe the bug In Obj context you can merging of the indices and data of coincident and identical vertex attribute values (Merge Vertex Indices) but there is no way to do it in USD. This makes textures stretching when you add subdivision on surface. If disable merging vertex indices in Obj you get the same result as in Solaris.

To Reproduce There is Houdini scene to reproduce issue: check.v001.hip.zip
