perf report: Introduce --stdio-color to setup the color output mode selection 

'perf report --stdio' will colorize entries with most hits and possibly
some other aspects of its output, but those colors gets suppressed if we
redirect the output to a non-tty, allow keeping the colors by adding a
new option, --stdio-color, now this use case will also output escape
sequences for colors:

  $ perf annotate --stdio-color | more
