patch 9.1.0184: Cursor pos wrong when clicking with conceal and wrap

Problem:  Cursor position wrong when clicking with conceal and wrap.
Solution: Use the virtual column of the last char for ScreenCols[] in
          boguscols.  Remove use of MAXCOL in ScreenCols[].  Rename
          third argument of wlv_screen_line() to "clear_end" as that's
          clearer what it does (zeertzjq).
