prop224: Add service rendezvous circuit relaunch

This introduces a callback to relaunch a service rendezvous circuit when a
previous one failed to build or expired.

It unifies the legacy function rend_service_relaunch_rendezvous() with one for
specific to prop224. There is now only one entry point for that which is
hs_circ_retry_service_rendezvous_point() supporting both legacy and prop224
circuits.
