 * Format XML string to match Grid 3's requirements
 *
 * Grid 3 requires specific formatting:
 * - Windows line endings (\r\n)
 * - Space before /> in self-closing tags: <Element /> not <Element/>
 * - Plain apostrophes instead of &apos;
 * - Specific tags expanded to full opening/closing format
 * - CDATA for empty/whitespace captions and <r> tags
 *
 * @param xml - The XML string to format
 * @returns Formatted XML string compatible with Grid 3
 *
 * @example
 * const formatted = formatGrid3Xml('<Grid><Cell X="0"/></Grid>');
 * // Returns: '<Grid>\r\n<Cell X="0" />\r\n</Grid>'
