isjunction for checking if a given path is a junction

[csm10495]

Feature or enhancement

(A clear and concise description of your proposal.)

Pitch

I’m proposing we add a isjunction method to os.path and a is_junction method to pathlib.Path. Both would return True if the given path is a junction. On Posix the API would exist, but would always return False as this tends to be a Windows-only thing.

We have similar logic to check for concepts like ismount, islink, etc. So i figure this would fit in.

There didn't seem to be any hard -1s to this proposal.
