tools: drop the AI class generators and their aidef data

The AI/Action/Query stub generators, the stub matcher and the IDA vfunc
renamers are no longer useful now that:
- every class has hand-edited source code
- IDB naming work has superseded the placeholder names used by the
  scripts

The scripts don't even import any more so we should just remove them.
