patch 9.1.1891: g<End> does not move to last non-blank in visual mode

Problem:  In visual mode, g<End> does not move to the last non-blank
          character when the end of a line is on the same line as the
          cursor (after v9.0.1753)
Solution: Move the cursor back by one position if it lands after the
          line (varsidry)

fixes: #18657
closes: #18658
