patch 9.2.0161: intro message disappears on startup in some terminals

Problem: intro message disappears on startup in some terminals
(chdiza, after v9.2.0139)
Solution: Only call set_shellsize() in handle_csi() if the reported
width or height actually differs from the current
Rows or Columns. (Foxe Chen)

fixes: #19656
closes: #19660
