Using existing library FileExplorerLib to replace the same logic in SecureBootConfigDxe to make the code clear. After using FileExplorerLib, the UI behavior for enroll PK will change, previously when select one PK file, commit/discard changes will return to Device Manager,press ESC will return to FileExplorer. Now using FileExplorerLib the behavior will keep same with enroll KEK/DB/..., commit/discard changes will return to Custom Secure Boot Options form and ESC will return to PK options form.
