Add WaterParticle shader and minor water shader tweaks

Introduced a new WaterParticle shader for rendering water particles with alpha blending. Made minor formatting and calculation adjustments in Water.shader and DefaultSetup.hlsl, and updated Variables.hlsl. Added corresponding .meta files for new shader assets.
