[analyzer] MIGChecker: Add support for more APIs.

Add more "consuming" functions. For now only vm_deallocate() was supported.

Add a non-zero value that isn't an error; this value is -305 ("MIG_NO_REPLY")
and it's fine to deallocate data when you are returning this error.

Make sure that the mig_server_routine annotation is inherited.
