[gnome-music/wip/jfelder/searchview-new-style: 9/15] searchview: Add view all buttons logic

[Marinus Schraal <mschraal src gnome org>]

commit 76a42ce01ac9ebfcf206b6364e919a458510ca92

    searchview: Add view all buttons logic
    
    Artists and Albums sections have limit on how large they can
    grow. When, the results in a section exceed the space available,
    clicking on a "view all" button opens a new page with the full
    results.
