With PaddingElimination optimizer, input1 of element-wise op may be
flattened like:
```
input1 (shape:[batch_size, seq_len, ...]) input1 (shape:[valid_tokens, ...])
\ \
\ input2 \ input2
\ / -----> \ /
\ / \ /
Element-wise Op Element-wise Op
```
So, the shape of input2 should be processed accordingly:
1. If input2.shape.dim_size <= input1.shape.dim_size-2, i.e. input2 has
no [batch_size, seq_len] at begining,
we needn't to process the shape of input2 because it's compatible with
the flattened shape of input1 (shape:[valid_tokens, ...]).
2. If the shape of input2 has the same dim_size with shape of input1 and
has [batch_size, seqlen] at begening,
to be compatible with flattened shape of input1, we need to insert
flatten pattern for input2 also,
which flatten the shape of input2 from [batch_size, seq_len, ...] to
[valida_tokens, ...].
3. (which done in this pr) In other case for shape of input2, like [1,
seq_len, ...] or [batch_size, 1, ...], we firstly need to expand it
to [batch_size, seq_len, ...] which is convenient to flatten. And then
insert flatten pattern.

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
