A virtual wxListCtrl with wxLC_HRULES which wasn't fully visible on
screen, i.e. didn't fit into the visible area of its parent window
(which included the case when the parent was a wxScrolledWindow, for
which it is normal and expected not to be able to fit all of its
children) got into an infinite repaint loop because of a RefreshRect()
call inside wxListCtrl::OnPaint().
Fix this by avoiding to call RefreshRect() added in 374db28747 (Fix
wxMSW ListCtrl drawing of horizontal rules for new items, 2016-05-04),
unless the current clipping rectangle is less than the actually
effective visible width and not the full client width, which can be much
bigger.
This still doesn't ensure that we don't enter into an infinite recursion
here, so it would be even better to call RefreshRect() at most once
before the next control change, but it's not clear when exactly this
"already refreshed" flag would need to be reset.
See #17158.
Closes #18850.
