[issue37921] Improve zipfile: add support for symlinks

[Pierre-Jean Grenier]

New submission from Pierre-Jean Grenier :

The module tarfile contains some methods for knowing whether an archive member 
is a regular file/a directory/a symlink. Apart from an "is_dir()" method, there 
was nothing alike in the zipfile module. For an on-going project, I needed to 
know whether an archive member was a symlink or not, to prevent zip symlinks 
attacks.

I thought this could be of used for other people, given I struggled a little to 
find a way of saying if an archive member is a symlink or not.

This is why I think adding support for symlinks in the zipfile module could be 
a good idea.
