Add alt-click usage context to toggle_icon component (#83123)

Browse Source 
## About The Pull Request

There is not much to this.
We make `toggle_icon` register an additional signal
`COMSIG_ATOM_REQUESTING_CONTEXT_FROM_ITEM` upon which we set the
alt-click usage context, and just add the `HAS_CONTEXTUAL_SCREENTIPS_1`
flag to the parent ourselves as we don't want the other effects of
`register_context()`.
## Why It's Good For The Game

Having working screentips is helpful.
