Finding out GN args used by CI/CQ bots

• Bots use mb tool, which is actually a "thin" python script that stands for "Meta-Build wrapper". Detailed docs here.
• Chromium builder configurations live at //tools/mb/mb_config.pyl file.

In order to find out, for example, the GN args used to build the official binaries of Lacros Chrome for amd64-generic boards, look for the builder group and builder name and pass them in to mb.py lookup scrip, as follows:

$ tools/mb/mb.py lookup --quiet -m tryserver.chrome -b lacros-amd64-generic-chrome
