### Description
Introduce new ORT L1 optimizer under RewriteRule category to fuse MatMul
+ BatchNormalization node. This optimizer look for a specific pattern
observed in one of the impacting customer models and fuse the Matmul and
Batchnormalization node into a Gemm node. For details on the pattern
matching and fusion please refer to the comment section of
`matmul_bn_fusion.cc`.
To visualize, this optimizer will replace following subgraph to a Gemm
node.
<pre>
MatMul GEMM
| |
Reshape ^ ---> Reshape ^
| |
Transpose ^ Transpose ^
|
BatchNormalization
Note: ^ means there can be >=0 occurrence(s) of that node.
Few example fusable pattern:
* - MatMul -> Reshape -> Transpose -> BatchNormalization ---> GEMM ->
Reshape -> Transpose
* - MatMul -> Reshape -> BatchNormalization ---> GEMM -> Reshape
* - MatMul -> Transpose -> BatchNormalization ---> GEMM -> Transpose
* - MatMul -> Reshape -> Reshape -> BatchNormalization ---> GEMM ->
Reshape -> Reshape
* - MatMul -> Reshape -> Transpose -> Reshape -> BatchNormalization --->
GEMM -> Reshape -> Transpose -> Reshape
* - MatMul -> BatchNormalization ---> GEMM
</pre>
Note: This optimizer may evolve in the future to be more generic in
terms of the pattern matching.
### Motivation and Context
- Why is this change required? What problem does it solve?
One of the user of ORT+DML ep needs this to better target the model to
DML. But this transformation applies more broadly, so added L1
optimizer.

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.
