Fix int() casting in torch.nn.RNN to have correctly traced JIT and ONNX graph. (#92970)

Fixes #91351
As for unit tests - in this PR I only fixed LSTM unit test to properly use dynamic axes and expose export issue by running test with same ONNX for additional inputs.
If the changes approved, we should also fix the rest of the tests (RNN/GRU and beyond).
I have verified the following updated tests are working with new code and failing with the old code:
test/onnx/test_pytorch_onnx_onnxruntime.py::TestONNXRuntime_opset_version_14_is_script_False_keep_initializers_as_inputs_True::test_rnn_name_lstm_nonlinearity_None_unilayer_bidirectional_no_initial_state_with_variable_length_sequences_with_dropout
