Ladybird: Use vector icons in the browser toolbar

Browse source 
We now load SVG icons (via the Qt resource system) and render them into
a QIcon (with normal and disabled variants) using system colors.
We also re-render them if the system color theme changes.

This instantly makes Ladybird look less foreign on my Linux box.

I drew the icons myself, and they could definitely be more optimized,
but this was my first time using Inkscape. :^)
