libweston: Introduce input-timestamps support 

Introduce code to support the implementation of the
input_timestamps_unstable_v1 protocol in libweston. This commit does not
implement the actual timestamp subscriptions, but sets up the
zwp_input_timestamps_manager_v1 object and introduces dummy request
handling functions for it, laying the foundation for timestamp
subscriptions for keyboard/pointer/touch to be added cleanly in upcoming
commits.
