Summary

Mods "[DinoMod] nest rework"

Purpose of change

Bugfixes, realism

Describe the solution

Applies bugfixes and improvements figured out in #56649 to all of the rest of the dino nests. Straw spawns at all nests. Dino predators have a guaranteed spawn and are on guard duty. Loot spawn and bone and feather spawns are fixed. Meat spawns at predator nests. Other dinos are on guard duty. Forest trash spawns at plant eating and bug eating nests

Describe alternatives you've considered

Figure out some kind of clever nesting mapgen thing to make this work better still

Testing

Game loads no errors, nests spawn and look right
