Builtin function for `ntpath.lexists`

[nineteendo]

Feature or enhancement

Proposal:

The lexists() implementation in genericpath use os.stat(). This is overkill on Windows. We should use a simpler builtin function. This can also benefit pathlib.Path.glob().

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
