chromeos/aura: Make login screen status area font non-bold.

chromeos/aura: Make login screen status area font non-bold.

This removes StatusAreaButton::Delegate's
GetStatusAreaFont() method and updates the text styles
returned by GetStatusAreaTextStyle() to include the font
weight.

I'm also removing the translucency from the light gray text
style so it'll match the header text on the WebUI login
page.
