Add multiple output support for dynamic fusion

* The dependency graph now can schedule any acyclic graph into
  a sequential list of operators. This is needed as the output
  operators now form branches in the graph.
* Fix the definition of input, output and intermediate tensors
  in GpuKernelComponentGroup to support non-linear but sequential
  list of operators.
* Add constraint on GpuOperatorGroup to enforce strictly linear
  fusion style, but allow output operator as the only form of
  branch.
