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
