LibGUI+LibGfx: Implement upside-down appearance for bottom-side tabs

Browse source 
GUI::TabWidget has long has a TabPosition::Bottom option, but we still
rendered the tab buttons the same as TabPosition::Top.

This patch implements a custom look for bottom-side tabs. I've done my
best to match the look of the top-side ones, but there might be some
improvements we can make here. :^)
