perf tools: Add 'trace_fields' dynamic sort key
The 'trace_fields' sort key is similar as 'trace' sort key, but it shows
each fields separately. Each event will get different columns as their
fields.
$ perf report -s trace_fields --stdio
# To display the perf.data header info, please use --header/--header-only options.
