patch 8.2.2064: terminal: cursor is on while redrawing, causing flicker

Problem:    terminal: cursor is on while redrawing, causing flicker.
Solution:   Switch the cursor off while redrawing.  Always add the top and
            left offset to the cursor position when not done already.
            (closes #5943)
