Creating an in progress craft finds items in nested containers

[mqrause]

Summary

SUMMARY: Bugfixes "Consume components in nested containers when crafting"

Purpose of change

Fixes #42777

Describe the solution

Created a recursive version of item_contents::all_items_top() and used it when consuming items from a container.

Describe alternatives you've considered

Testing

See issue.

Additional context

item_contents::all_items_top() and item_contents::all_standard_items_top do the same thing, but the former achieves it by iterating over a static vector while the latter does it by checking item_pocket::is_standard_type, which returns true on exactly the elements that are in the static vector. If that's just a coincidence and might change, the names of the methods I created should be changed to something different. all_standard_items_top currently isn't used anywhere, though.
