[fractal/wip/cdavis/next-style-cleanup: 5/6] components: Add RoomTitle component

[Christopher Davis <christopherdavis src gnome org>]

commit 524873a7b85cb903c185da1482f24c62572ad84e
Author: Christopher Davis <christopherdavis gnome org>
Date:   Fri Jun 25 13:49:18 2021 -0700

    components: Add RoomTitle component
    
    Adds a custom RoomTitle widget in place of AdwWindowTitle.
    This will allow us to have markup in titles and subtitles,
    and allow us to have tooltips set appropriately.
