TOOLS: Update convert_dxa batch file

 - Merge the two existing batch files into a single file (#2043446)
 - Check for needed tools before proceeding
 - Use the new scummvm-tools-cli tool
 - Properly return to original folder on exit
 - Add audio parameter options
 - Add option to pass tools and Rad tools paths as environment variables, with fallback to default paths
