Store the result of wxWindow::NewControlId() in wxWindowIDRef.

The result of calling NewControlId() must be assigned to wxWindowIDRef to be
accounted for correctly, otherwise the id was marked as free while a reference
to it still existed resulting in asserts in id management code when we
attempted to reuse it.

Closes #11604.
