Moves yet more things from attackby() to item_interaction() (#96672)

## About The Pull Request

20 files converted, that last one's just to make the return value
explicit. The syndicate bomb `attackby()`'s only half converted, because
half of it was actually meant for `attackby()`.

## Why It's Good For The Game

only like, 250 files to go. Slow and steady.

## Changelog
