Add missing input flags to aidl and add missing definitions

To ensure that the future updates are consistent across java, cpp, and
rust, we move all of motion event flags to aidl. That will be the
source of truth for those constants. That still doesn't ensure that in
the future updates, we forget to add these to all the languages, but at
least now it will be much easier to do so.
