Benjamin Cheng 9ef026e804 input/cursor: pass gesture events to clients
Some wayland clients (mostly GTK3 apps) like eog or evince support
gestures like pinch-to-zoom. These gestures are given to clients
via the pointer_gestures_v1 protocol. This is already supported in
wlroots, so we just need to hook up the events here in sway.

Fixes #4724
