XNNPACK Integration by default

XNNPACK backend is supported and enabled via a build-time opt-in mechanism. Can be enabled by default?

Hi @Jack_Daniels ,

while building the tflite you have to run the below command to enable tflite with xnnpack support

bazel build --define tflite_with_xnnpack=true //tensorflow/lite:libtensorflowlite.so

Thank You.
