[python] Add `walk_with_filter` to walk subset of IR #7591

This adds `walk_with_filter` python method to invoke callbacks only for subset of operations. We require GIL to call python function so this could improve performance of the tools based on Python API. ``` Starting walk_with_filter walk_with_filter elapsed time: 0.005462 seconds cnt=1 Starting operation.walk operation.walk elapsed time: 1.061360 seconds cnt=2 ```
