Refactor lighting code and add wave support to shaders

Modularized lighting calculations by introducing DefaultSetup.hlsl and Lambert.hlsl includes, and updated BlendinShader, LitParticles, and Water shaders to use these macros. Added new wave-related properties and logic to Water.shader for enhanced wave effects. Improved maintainability and consistency across shaders by centralizing light and Lambertian diffuse calculations.
