Convert tflite_delegate/Android.mk to Android.bp

1. Convert the Make file to a Soong one;
2. The first module has been converted and moved to the directory where
the src files locate;
3. The Android.mk file had been included by another .mk file, so the
include line has been removed from that .mk file (since it has been
converted into .bp file).
