[issue32839] Add after_info as a function to tkinter

[Serhiy Storchaka]

> Since events are removed from Tcl once that are invoked, how would the dictionary be cleaned up?  Would after_info need to be polled every once in a while to clean up the dictionary or would it just exist until the object is destroyed?

Good question. Currently the reference to a callable is kept in the dict  until the object is destroyed. This can be considered as a bug (see issue1524639).
