Fix the issue where the "Custom" pipeline cannot use post-processing in WebGL 1.0.

Greptile Summary

This pull request addresses an issue where the "Custom" pipeline was unable to use post-processing effects in WebGL 1.0 contexts. The changes focus on optimizing the rendering pipeline, particularly in the management and updating of descriptor buffers.

Key changes include:

• Refactored descriptor buffer management for more efficient updates
• Introduced granular control over constant buffer updates with new functions
• Modified the updatePerPassUBO function to use optimized update methods
• Improved handling of lights and shadows for better performance in WebGL 1.0
• Optimized creation and management of descriptor buffers to reduce unnecessary updates

These optimizations should enable post-processing effects to work properly with the "Custom" pipeline in WebGL 1.0, while also potentially improving overall rendering performance.
