perf(column): keep track of number of lines that hold up the 'signcolumn'

Browse Source 
Problem:  The entire marktree needs to be traversed each time a sign is
          removed from the sentinel line.
Solution: Remove sentinel line and instead keep track of the number of
          lines that hold up the 'signcolumn' in "max_count". Adjust this
          number for added/removed signs, and set it to 0 when the
          maximum number of signs on a line changes. Only when
          "max_count" is decremented to 0 due to sign removal do we need
          to check the entire buffer.

          Also replace "invalid_top" and "invalid_bot" with a map of
          invalid ranges, further reducing the number of lines to be
          checked.

          Also improve tree traversal when counting the number of signs.
          Instead of looping over the to be checked range and counting
          the overlap for each row, keep track of the overlap in an
          array and add this to the count.
