Make NXP batch norm tests runnable in BUCK

[JakeStevens]

Summary:
Make the NXP test_batch_norm_fusion tests compatible with the BUCK build
system. The tflite import in executors.py is made optional since
tensorflow/tflite_runtime are not available in the BUCK environment. The tests enabled do not rely on the functionality enabled by tflite.

This import is never used. Are you internally using Python <3.10 and need this for type annotations (such as | (union))? Or what is the purpose of this?

Edit: Now I see it is required for the type hint:

class TFLiteExecutor:
    _interpreter: tflite.Interpreter

I assume the first commit is just a dependency, and only the second commit is meant for review in this PR. Perhaps it would be useful to state that explicitly. Otherwise, LGTM

Yes, just a dependency but not strictly needed, rebased so it is clear only one commit here and merging.
