Separate build functions from SConstruct
Placed in scripts/build Streamline scons options with OptionsClass in scripts/build/option_handler.py Move `show_progress` cache function to scripts/build/cache.py Move `GlobRecursive` function to scripts/build/glob_recursive.py Make environment clone of godot-cpp's build Prevents environment leakage into godot-cpp
