backends: Add MetaInputSettings

This object internally keeps track of the relevant input configuration, and goes through its vmethods in order to apply the configuration on the backend-specific devices. So far, only mouse/touchpad settings are actually attached to GSettings changes. ::set_matrix(), meant for tablets/touchscreens, is not hooked yet. One caveat is that meta_input_settings_create() may return NULL if the backend does not own the windowing system (wayland nested on X11 being the one case), and thus device settings can't be changed freely. https://bugzilla.gnome.org/show_bug.cgi?id=739397
