Clean up camera shader parameter setup

[mvaligursky]

Removes redundant uniform setters and consolidates camera parameter setup code.

Changes:

• Removed unused camera_near and camera_far uniform setters from the renderer - these values are already provided via camera_params and no shaders consume the standalone uniforms
• Added Camera.fillShaderParams() method to centralize camera params array population
• Updated renderer, TAA render pass, and CoC render pass to use the new method, eliminating duplicate code
