d2c3d8eb - Add Bert/GPT2 fusion change for new attribute mask_filter_value in ORT optimizer (#14333)

Add Bert/GPT2 fusion change for new attribute mask_filter_value in ORT optimizer (#14333) ### Description <!-- Describe your changes. --> The changes correspond to specify the mask_filter_value in attention attribute. However, the ORT optimizer cannot fuse SkipLayerNorm/Attention/EmbedLayerNorm with the most recent transformers. So this PR may only address this issue with some older version of onnx models(e.g the one used in the unittest) ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> Co-authored-by: Ubuntu <wy@v100-2.0cdb2e52twzevn1i4fi45bylyg.jx.internal.cloudapp.net>
