Fix segfault on using spillable comestibles (aluminum cans/tin cans)

[alanbrady]

Summary

SUMMARY: Bugfixes "Fix drinking from 'aluminum can' segfault and fix tin cans more"

Purpose of change

PR #25017 broke using aluminum cans and caused a duplication bug when eating from tin cans from inventory.

Inventory/item code is hard.

Describe the solution

This fixes it by adjusting the placement of the call to handle_spillable_contents() to a more appropriate place in the flow of consuming an item. We also check if handle_spillable_content handled our comestible or not. If it did we need to remove it from inventory.

This also fixes a small issue in usability where if you:

1. eat soup from a sealed tin can
2. get query asking what to do with rest of soup
3. choose e) 'Consume It'
4. item gets placed on the ground without further queries

User should expect to see another dialog box asking them what to do about the rest of the soup instead of just defaulting to put it on the ground for the remaining portions. This, however was actually a preexisting issue if you tried to put a spillable bucket in a vehicle and chose 'Consume It', the same behavior is observed and the same fix will fix them both.

Additional context

The original issue attempted to be treated here is when eating from a vehicle, the item just gets spilled on the ground instead of handled gracefully. See #18168
