perf ui stdio: Add way to setup the color output mode selection 

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.
