[Build] Update scripts to use dyld_info (#60532)
* [Build] Update scripts to use dyld_info
dyldinfo has been deprecated and will no longer be available on newer Xcode releases. It has been replaced with dyld_info. To stay compatible with older releases, we are still falling back to dyldinfo, if dyld_info is not available.
