Disable colorized output for flutter/packages LUCI tests #89392
Description
The colorized output that the tool does for most commands now is great locally and on Cirrus, but awful for the LUCI bots. E.g.:
============================================================
|| Running for wifi_info_flutter_platform_interface
============================================================
�[0m
�[90mSKIPPING: Platform interfaces are not expected to have integration tests.�[0m
------------------------------------------------------------
Run overview:
android_alarm_manager - �[90mskipped�[0m
android_intent - �[90mskipped�[0m
battery/battery - �[90mskipped�[0m
battery_platform_interface - �[90mskipped�[0m
We should add a flag to the tool that disables all colorized output and use that for the LUCI runs.
