Utils: Introduce InfoLabel

Utils::InfoLabel is meant to replace around 30 custom implementations of
a QHBoxLayout with an pixmap QLabel and a text QLabel.

Instead of fiddling with pixmaps, the user of InfoLabel can set an enum
for info/warning/etc... type. Internally, a globally shared QIcon is
used. The usage of QIcon ensures that @1x, @2x and hybrid cases are
handled.
