Improve hunger and thirst warning icons (#18390)

Changes the icons for the three stages of hunger and thrist to be more visually distinct from their other stages and not rely on color coding. This makes it more colorblind-friendly.

Create a flashing animated sprite for Starvation and Parched states, making them much more noticable with the intention to draw attention towards managing these states.
