backends/x11: Support input-synaptics, if present.

Add support for configuring the Xorg synaptics touchpad driver.

Turns out it's very simple to support both libinput and synaptics
simultaneously, both under the heading of XI2.

gtk-shell: Work around non-working startup notifications

GNOME Shell relies on the MetaScreen::startup-sequence-changed signal,
which is tied to (lib)startup-notification and therefore X11. As a result,
when we remove the startup sequence of a wayland client, GNOME Shell will
not be notified about this until startup-notification's timeout is hit.
As a temporary stop-gap, go through XWayland even for wayland clients,
so that the signal is emitted when expected.

theme: use gtk_render_icon_suface to paint button icon

This will properly take care of the icon transformations
and of the shadow.
