Note the first commit in this PR has its own pull request here since it seemed self-contained:
#57082

• [ONNX] simplify batch_first logic in RNN tests

• [ONNX] support GRU with packed input in scripting mode

This required two changes:

• Add as_tensor to symbolic_opset9.py
• Change torch::jit::pushPackingPastRnn to recognize and properly
  replace another use of the batch_sizes output of prim::PackPadded.
  Previously the code assumed that the first use was as input to the
  RNN operator. However in some cases, it is also used to compute
  max_batch_size. For example in this code:
  https://github.com/pytorch/pytorch/blob/febff45/torch/nn/modules/rnn.py#L815-L815

With these changes the GRU tests now pass in scripting mode for opset
version >= 11.
