Make git cl status use bold colors

Normal weight colored text can be hard to read, especially over Chrome
Remote Desktop (video compression treats chroma harshly). Git colors can
be made more readable by editing .gitconfig, but git cl colors are hard
coded. This hard codes them to all be bold, for greater readability and
effective brightness, and changes the still-too-dim-over-CRD blue to red.
