* MatMulInteger + post op fusion
This fuses MatMulInteger with upto 32 binary/elementwise
operators if running on the oneDNN execution provider.

* Remove the un-needed transformer
The MatMulIntegerToFloat transformer is not needed since
the transform done is handled by the MatMulIntegerBinaryEltwise
transformer code.

* Refactor of the post op trasformer code
This separates the code that finds the post op
nodes for MatMul and MatMulInteger to reduce code
repetition.
