Keep original name during fusion (#20097)

### Keep original name during fusion

This could be helpful to know where the fused node coming from, I feel
this is very useful when debugging the execution order issues between
different transformer layers.

For example:

- A node named
`/_original_module/model/layers.1/self_attn/MatMul/MatmulTransposeFusion//MatMulScaleFusion/`
goes through two fusion paths in the 1st transformer layer - e.g.
`MatmulTransposeFusion` and `MatMulScaleFusion`.

-
`/_original_module/model/layers.2/post_attention_layernorm/Mul_1/SimplifiedLayerNormFusion/`
node is a fused node by `SimplifiedLayerNormFusion`.
