fix(UI): more improvements to visibility of bionic scanning

[chaosvolt]

Purpose of change

This implements yet more adjustments and improvements related to harvesting bionics.

Describe the solution

1. In game.cpp, set add_corpses so that the butchery menu's list of monster corpses visually marks corpses that have CBMs detected in them, showing them with the same (bionic detected) text on the end like their item form does. This makes it easier to remember which ones out of a pile of bodies have had a CBM detected.
2. In item.cpp, changed item::tname so that scanned corpses gain a either (scanned) or (bionic detected) depending on if they have a bionic in then. This helps the player actually tell that the scanner is working by marking corpses that've been scanned but have no CBMs in them.

Testing

1. Compiled and load-tested.
2. Spawned in and debug-killed a bunch of shocker zombies.
3. Scanned the pile with a bionic scanner.
4. Corpses without bionics showed as scanned, ones with bionics showed the usual tagtext.
5. Stood over a pile, some correctly show the info alongside the monster name.
6. Separated them into two piles for with and without CBMs detected.
7. Confirmed that the pile of ones with detected CBMs all show the added text in butchery menu, while the ones only marked as scanned don't.
8. Made sure only the corpses could show as scanned and not the items nearby.
9. Murdered my NPC friend, his body also shows as scanned after running by with the scanner active.
10. Checked affected files for astyle.
