patch 9.0.1783: Display issues with virt text smoothscroll and showbreak

Problem:  Wrong display with wrapping virtual text or unprintable chars,
          'showbreak' and 'smoothscroll'.
Solution: Don't skip cells taken by 'showbreak' in screen lines before
          "w_skipcol". Combined "n_skip" and "skip_cells".

closes: #12597
