GTK: Implement the bookmark bar chevron.
I didn't use the native GtkToolbar version of this because, as usual, GTK doesn't give us enough flexibility to do what we want. But it wasn't too hard or super hacky to re-implement it.
The chromium version (and hence the Windows version) looks bad. This is not my fault. I don't know why it points right rather than down, when the menu pops down, not to the right. This is why I used a down arrow for the GTK version rather than matching with a right arrow.
