promisor-remote: keep accepted promisor_info structs alive
In filter_promisor_remote(), the instances of `struct promisor_info` for accepted remotes are dismantled into separate parallel data structures (the 'accepted' strvec for server names, and 'accepted_filters' for filter strings) and then immediately freed. Instead, let's keep these instances on an 'accepted_remotes' list. This way the post-loop phase can iterate a single list to build the protocol reply, apply advertised filters, and mark remotes as accepted, rather than iterating three separate structures. This refactoring also prepares for a future commit that will add a 'local_name' member to 'struct promisor_info'. Since struct instances stay alive, downstream code will be able to simply read both names from them rather than needing yet another parallel strvec.
