Make wave generation parameters available to other shaders

[QuinnLeavitt]

I think it could be useful to make the wave generation parameters available to other shaders to use because it would allow the splash particles to move in the direction of the wind and be affected by the wind speed. I could also see higher choppiness/windspeed potentially affecting the amount of bubbles that appear near the surface.

If we can describe how we'd like that to be implemented here, I'd gladly do the legwork of implementing it.

This may be something we should maybe hold off on doing until the tool script PR is approved so we don't have to redo as much work.
