[mutter/wip/carlosg/input-thread: 35/43] backends/native: Shuffle keyboard a11y signal connection into MetaSeatImpl

[Carlos Garnacho <carlosg src gnome org>]

commit 57c29fd361e65afefdc54437d41d61a41dd427fa

    backends/native: Shuffle keyboard a11y signal connection into MetaSeatImpl
    
    This signal gets emitted in the input thread, and does things that
    belong to it. Make it clear by moving to the MetaSeatImpl.
