feat(wayland): touch, with the first finger standing in for the pointer

Browse source 
The seat's wl_touch was never bound, so a touchscreen could not drive a
window at all. Every finger is now reported through onTouchDown, onTouchMove,
onTouchUp and onTouchCancel (TouchPoint: the compositor's id and the
position in physical pixels). The first finger down also enters the window —
Device::focusedWindow and the pointer serial the clipboard needs — presses
the left button, moves it and releases it when it lifts, so an application
written for a pointer works on a phone as it is.
