patch 9.2.0905: MS-Windows: ghost cursor with ligatures

Problem: With ligatures enabled, a ghost cursor can be left on screen
because the cursor is marked valid before the ligature
cleanup, which redraws the cell with gui_screenchar() and
invalidates the cursor again (ubaldot)
Solution: Set gui.cursor_is_valid only after the ligature redraw is
done, so it isn't cleared afterwards (Foxe Chen).

fixes: #20916
closes: #20924
