Add anapic script to upload diffs for review

These diffs are between the hidl2aidl tool output and the existing
interface definition.
It generates 2 CLs, the second one is more readable and shows going from
the hidl2aidl output TO the existing definition today.

example:
anapic_hidl2aidl_review.sh android.hardware.boot@1.2

Test: run example command and verify output
Bug: none
