tests: Add paint-node test
This is a very simple test, mostly intended as a demonstration of the new client<->compositor breakpoint infrastructure. It ensures that for a simple test surface, a paint node has been created in the output's paint-node list, reflecting the properties of the attached buffer. This is an example of properties which are not observable by regular clients. Signed-off-by: Daniel Stone <daniels@collabora.com>
