feat(balance): allow pulping zombify_into corpses

[chaosvolt]

Purpose of change

This change aims to make it so you can pulp dead feral humans to keep them from reviving like you would with regular zombies, instead of the only option being to butcher them (or wait for them to revive, kill their zombie form, them pulp that).

WIP because I'm out and about on laptop currently, will test then mark as ready when I get home.

Describe the solution

1. In activity_handlers.cpp, set it so activity_handlers::pulp_do_turn treats coprses with zombify_into as valid to pulp.
2. In cata_tiles.cpp, set cata_tiles::draw_zombie_revival_indicators to also check for unpulped monsters with zombify_into set for the sake of displaying the "stuff that should be pulped" indicator. Nested in a check for is_corpse to avoid potential access violation shenanigans I encountered during initial testing.
3. In handle_action.cpp, also set it so smash considers corpses that have zombify_into valid to pulp.
4. In item.cpp, changed item::color_in_inventory so that corpses with zombify_into show as yellow, just as ones with REVIVES do, and set it so the corpse being pulped reliably invalidates this.
5. Also in item.cpp, changed item::process_corpse so the part that handles zombify_into also checks that the corpse isn't pulped before changing monster type.
6. In map.cpp, set it so map::smash_items can correctly spot corpses with zombify_into for smashing.

Testing

Started with a benchmark test in my playthrough build by debug-killing a bunch of feral humans, changing time forward 5 days, then waiting 5 minutes. As expected, they soon all converted into un-revived zombie corpses and started to get back up.

1. Compiled and load-tested.
2. Spawned in some feral humans and debug-killed them.
3. Observed that the bodies now show as yellow.
4. Pulped half of the bodies, they can now be pulped, stop showing as yellow afterward and can only be pulped once.
5. Advanced time forward 5 days.
6. Waited five minutes, only the intact feral human corpses converted into zombies and reanimated.
7. Also spawned in some regular zombies and repeated above tests, to confirm that they still displayed, pulped, and reanimated as normal.
8. Tested a save with Dinomod, spawned in a pair of T. Rexes and confirmed they show as pulpable when slain, and pulping them works.
9. Checked affected files for astyle.

Additional context

I'm 90% certain DDA does this too but dunno what PR it is nor if there's any difference in how they do it.

Checklist

[DrPariah]

Will this catch all 'zombify_into' entries? Asking because dinosaurs from Dinomod also have this issue. Sent from Yahoo Mail on Android

[chaosvolt]

It should catch anything that uses zombify_into at all, yeah. About to test now that I'm back home.
