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

Browse source 
'perf annotate --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
