Move appropriate `CommandLineBuilder` methods to properties on `CommandLineConfiguration`

[jonsequitur]

        // Technically "cancel" is a verb, but I feel like the method is actually implying "Set" as the main verb and CancelOnProcessTermination is what the property would be called.
        // So, consider making this a property instead of a method when moving it.
        public static CommandLineBuilder CancelOnProcessTermination(this CommandLineBuilder builder);
        // These Enables also look like properties.
        public static CommandLineBuilder EnableDirectives(this CommandLineBuilder builder, bool value = True);
        public static CommandLineBuilder EnableLegacyDoubleDashBehavior(this CommandLineBuilder builder, bool value = True);
        public static CommandLineBuilder EnablePosixBundling(this CommandLineBuilder builder, bool value = True);
