Creates an interface target for `LinalgRelayoutInterface`. This is primarily to reduce the dependency of `Tensor` on `Linalg` to the required minimum. For context and rationale, see: * https://github.com/llvm/llvm-project/issues/127668 Note, I also took the liberty of renaming `LinalgRelayoutInterface` as `RelayoutOpInterface` (removed `Linalg`, added `Op`).
