Remove TFLM specific code from lite/kernels/op_macros.h

With TFLM moving to its own repository, we should no longer have a dependency
from TfLite to TFLM.

tensorflow/tflite-micro#275 adds a TFLM-specific
implementation of op_macros.h in the TFLM tree and we can now remove all the
TFLM code from the tensorflow tree.
