zbus 3.5.0

• Derive Hash for MessageType so it can be used as a key in hashmaps.
• Add API to represent match rules. These are used to subscribe to signals
  mainly.
• Add fdo::DBusProxy::{add_match_rule,remove_match_rule}, that are
  {add_match,remove_match} replacements that make the same
  underlying D-Bus calls but make use of the new MatchRule type. We also
  deprecate the {add_match,remove_match} to discourage use of these less
  type-safe versions.
• ProxyBuilder::uncached_properties sets given list Instead of
  appending. The usecase is for users to set it only once.
• ObjectServer should handle methods destined to unknown names if no
  names are registered. We were only doing this for p2p case but we should
  do this for bus case well. Otherwise it breaks things for folks who were
  using fdo::DBusProxy::request_name along with ObjectServer for any
  reason.
• Bump zvariant requirement to latest release.
