Adjust solution size on slicing/eating food

[whatston3]

About the PR

When food is bitten or sliced, this adjusts the capacity in the food - for instance, you shouldn't be able to replace the bite of chocolate cake you just ate with ketchup.

Why / Balance

Separated out at the request of @dvir001 - this was added into the Goblin Food Rework PR (#1159) a long time ago, and has been stuck in limbo and needs more work. Feature's simple enough and easy to verify that it should be done separately.

How to test

1. Spawn an apple.
2. Open the solution editor on the apple.
3. Take a bite. Note that the solution capacity decreases.
4. Spawn an apple cake and a knife.
5. Cut the cake. Note that the solution capacity decreases proportionally with the number of slices in the cake.
