[issue18283] shutil.which() should support bytes

[STINNER Victor]

STINNER Victor added the comment:

Almost all functions of the shutil module support bytes filenames. I tested shutil.copyfile(), shutil.ignore_patterns(), shutil.copytree(), shutil.rmtree() and shutil.move().

I only found one function which only support Unicode filenames: shutil.make_archive().
