Shader compilation time is higher in 2021.3 than in 2020.3

The reason for the increased shader compilation times, in this case, was due to an increase in array sizes for Additional Light Shadow in URP Shaders. That change has now been reverted. Additionally, we remove any shader parameters for Additional Light Shadows if the feature is disabled in the URP Asset. To further improve compilation times we have also added Shader Prefiltering, which helps with stripping out unused shader variants early in the shader processing stage.
