protocol: Add test screenshot capability

Browse Source 
This adds a capture_screenshot request which returns an image of the
screen in the client-supplied wl_buffer for the given display output.

A 'done' event is used to indicate when screenshotting has finished and
the wl_buffer is ready to be read.
