perf top: Add -w option for setting column width
Add -w/--column-widths option like perf report does so that users are
able to see symbols even with some very long C++ library/functions.
It can be a list separated by comma for each column.
$ perf top -w 0,20,30
The value of 0 means there's no limit.
