perf annotate browser: More clearly separate columns
The first column (columns in the near future) are for the per line event
overhead(s), that only appear when they are not zero.
To clearly separate it, add back a solid vertical line, with just one
colour, not influenced by the per line overheads.
Then have the addr/offset column, then optionally the dynamic
(static in the future) jump->target arrows, if 'j' enables it.
Then the instructions.
