Refactor Moonlight lighting system in shaders

Replaces direct variable declarations and code blocks related to 'MoonsLight' with a new 'MoonlightGlobalVariables' macro included from Variables.hlsl. Adds OutLoopSetup macro for loop setup, updates all relevant shaders to use the new macros, and renames comments and identifiers from 'MoonsLight' to 'Moonlight' for consistency. Removes the obsolete MoonsLight.cingc include and its meta file.
