[MIRROR] Adds screentips to the customizable food datum [MDB IGNORE] (#17709)

* Adds screentips to the customizable food datum (#71444)

## About The Pull Request

Straightforward follow up to doing this to processable.dm, adding
screentips to a basic cooking thing so that there's never confusion
about what is and isn't a valid ingredient for a specific food. Also
changes some to_chat stuff into balloon alerts.

As part of this, customizable food now calculates the valid ingredients
in its own variable, which means that if anyone wants to change how
valid ingredients work separately from the other parts of how this datum
works.

I'm unsure of the wording for the tip, i think that having it just be
"add" works but it doesn't hurt to start with the possibly unnecessarily
specific "add [item you are holding]"

## Why It's Good For The Game

Adding in screentips as parts of modules like this is good and I like
balloon alerts more than to_chats for really small and fast "you cant do
that!" type stuff.
