ls-files: align format atoms with git ls-tree

Users sometimes want all format atoms of git ls-files --format to be compatible with the format atoms of git ls-tree --format [1]. However, git ls-files --format lacks the %(objecttype) and %(objectsize), %(objectsize:padded) atoms compared to git ls-tree --format, causing incompatibility. Therefore, these atoms are added to the --format of git ls-files to resolve the issue of incompatibility.

%(objecttype): get the object type of the file which is recorded in the index. %(objectsize): get the object size of the file which is recorded in the index, ("-" if the object is a commit or tree). %(objectsize:padded):
same as %(objectsize), but with a padded format.

v1: add %(objecttype) and %(objectsize) atos to git ls-files --format.
