backend/wayland: add support for explicit sync

Browse source 
wl_buffer.release event delivery becomes undefined when using the
linux-drm-syncobj-v1 protocol, so we need to wait for buffer
release via a timeline point instead.

The protocol requires both wait and signal timelines to be set, so
we need to create one when the compositor only supplies a wait
timeline.
