feat(extmarks): add virt_text_repeat_linebreak flag (#26625)

Browse Source 
Problem:  Unable to predict which byte-offset to place virtual text to
          make it repeat visually in the wrapped part of a line.
Solution: Add a flag to nvim_buf_set_extmark() that causes virtual
          text to repeat in wrapped lines.
