Olivier Goffart 686f5e43e2 Widget style: simplify -light/-dark handling
Instead of having all style duplicated and re-using a base, we just hack
into the funciton that queries the dark/light theme based on the style
suffix known at compile time.

This removes one of the problem that happens when trying to work on the
widget style with the extension, as it relies on include path hacks
