[mutter] wayland/feedback-actor: Use float for position and anchor

[Jonas Ådahl <jadahl src gnome org>]

commit 7275cf60bdfa353e43e8176253f8e170b838e7a5
Author: Robert Mader <robert mader posteo de>
Date:   Mon Aug 26 14:14:18 2019 +0300

    wayland/feedback-actor: Use float for position and anchor
    
    To be correct with fractional scaling. Furthermore, we currently
    use it only with ClutterPoint values, which are floats already.
