Relate _curses.wrapper return type to its function arg (#2353)

Browse Source 
`curses.wrapper` returns the return value of the function it is passed,
but its function argument is declared as `Callable[..., Any]` while its
return type is `None`. This changes the definition of `curses.wrapper`
to use a `TypeVar` that relates the return type of its function argument
to its own return type.
