Charge removal side effects 3: unmigrated item spawns

Describe the bug

There are countless places that allow inline definitions of itemgroups or other shorthand definitions that were not caught by the automated script, so all of these are now broken and only spawn single items instead of the defined charges or default charges of the item.

Where to find these cases:

1. Inside regular itemgroups
   • "distribution" or "collection" members inside the "items" or "entries" array
   • simple itype entries inside the "items" array
2. Professions
   • lots of simple itype entries, although probably not many that spawn with comestibles
3. Mapgen (and vehicles?)
   • this one is the most tricky, because there are many different ways to define spawns and I definitely don't know all of them
4. Recipe byproducts
   • haven't actually confirmed that one, but it's probably an issue?
5. Probably other places I forgot
   • comments appreciated
