2022-02-21[Net] Optimize object cache notification send for single peer.Fabio Alessandrelli
It used to always cycle all the peers when checking which one needed to be notified, now it only does that when the target is multiple (i.e. broadcast or exclusion).
2022-02-21[Net] Fix multi-peer path-only replication.Fabio Alessandrelli
It used to check if a net_id was ever assigned to that node to detect when to send the path confirm to the remote peer. This is wrong, because the same net_id is shared for all the remote peers, but sent one by one. Instead we now check if it's either not assigned or if the assigned net_id is a cache ID, and in that case ensure that the remote peer has been notified. This can be further improved by unifying the cache interface, but for now it's a fast fix to get path-only sync to work.

2022-02-05[Net] Move RPC, Node cache out of MultiplayerAPI.Fabio Alessandrelli
Now uses two interfaces so it can be overridden in the future, and core no longer depends on Node. The interfaces are implements in scene/multiplayer. Replaces root_node with root_path. Remove all Node references from MultiplayerAPI.
2022-02-04[Net] New replication interface, spawner and synchronizer nodes.Fabio Alessandrelli
Initial implementation of the MultiplayerReplicationInterface and its default implementation (SceneReplicationInterface). New MultiplayerSpawner node helps dealing with instantiation of scenes on remote peers (e.g. clients). It supports both custom spawns via a `_spawn_custom` virtual function, and optional auto-spawn of known scenes via a TypedArray<PackedScenes> property. New MultiplayerSynchornizer helps synchronizing states between the local and remote peers, supports both sync and spawn properties and is configured via a `SceneReplicationConfig` resource. It can also sync via path (i.e. without being spawned by a MultiplayerSpawner if both peers has it in tree, but will not send the spawn state in that case, only the sync one.
