wayland: Get implicit grab serial information from tablet devices

Browse Source 
If a tablet device is used to perform actions like window moving or resizing,
GTK must provide the correct implicit grab serial number over Wayland to Mutter
in order for the action to succeed. This commit adds tablet support to the
implicit serial getters.
