Subject: fix(display): adjust winline info for concealed lines below last line
 (#32708)

Problem:  Last line in a window does not store correct `wl_lastlnum` if
          lines below it are concealed (resulting in e.g. incorrect
          cursor row).
Solution: Increment `wl_lastlnum` while it points to a line above a
          concealed line.
