In --stdio we turn off color output when the output is not a tty, which is not always desirable, for instance, in: perf annotate | more the 'more' tool is perfectly capable of processing the escape sequences for colored output. Allow using the existing logic for .perfconfig's "color.ui" to be used from the command line by providing a stdio__config_color() helper, that will be used by annotate and report in follow up patches.
