[Net] New replication interface, spawner and synchronizer nodes. 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.

[Net] Modularize multiplayer, expose MultiplayerAPI to extensions. - RPC configurations are now dictionaries. - Script.get_rpc_methods renamed to Script.get_rpc_config. - Node.rpc[_id] and Callable.rpc now return an Error. - Refactor MultiplayerAPI to allow extension. - New MultiplayerAPI.rpc method with Array argument (for scripts). - Move the default MultiplayerAPI implementation to a module.

[Net] New replication interface, spawner and synchronizer nodes. 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).

New MultiplayerSynchornizer helps synchronizing states between the local and remote peers, supports both sync and spawn properties and is configured via a `SceneReplicationConfig` resource.

Add peer visibility to MultiplayerSynchronizer. MultiplayerSynchronizers can now be configured to limit their visibility to a subset of the connected peers, if the synchronized node was spawned by a MultiplayerSpawner (either automatically or via custom spawn) the given node will also be despawned remotely. The replication system doesn't have the logic to handle subspawn directly, but it is possible to handle them appropriately by manually updating the visibility of the parent before changing the one of the nested spawns via the "update_visibility" function. The visibility of each MultiplayerSynchronizer can be controlled by adding or remove filters via "[add|remove]_visibility_filter(callable)". To further optimize the network code, visibility filters can be configured to be automatically updated during idle or physics frame, or set to always require manual update (via the "update_visibility" function).

[MP] Allow multiple synchronizers per node. The same node can now be controlled by multiple synchronizers at once. Spawn visibility is composed in OR across multiple synchronizers (i.e. if any synchronizer is visible to the peer, the object will be spawned). Synchronizers controlling spawned nodes can now have a different authority then the one spawning the node, in that case, the spawn variables for that specific synchronizer are simply ignored (other synchronizers with the same authority of the spawner will correctly synchronize variables on spawn). The SceneReplicationState class has been completly removed, since it was bloating the implementation, the state is now simply stored in the SceneReplicationInterface.

Add peer visibility to MultiplayerSynchronizer. MultiplayerSynchronizers can now be configured to limit their visibility to a subset of the connected peers, if the synchronized node was spawned by a MultiplayerSpawner (either automatically or via custom spawn) the given node will also be despawned remotely. The replication system doesn't have the logic to handle subspawn directly, but it is possible to handle them appropriately by manually updating the visibility of the parent before changing the one of the nested spawns via the "update_visibility" function. The visibility of each MultiplayerSynchronizer can be controlled by adding or remove filters via "[add|remove]_visibility_filter(callable)". To further optimize the network code, visibility filters can be configured to be automatically updated during idle or physics frame, or set to always require manual update (via the "update_visibility" function).

[Net] New replication interface, spawner and synchronizer nodes. 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.

[MP] Allow multiple synchronizers per node. The same node can now be controlled by multiple synchronizers at once. Spawn visibility is composed in OR across multiple synchronizers (i.e. if any synchronizer is visible to the peer, the object will be spawned). Synchronizers controlling spawned nodes can now have a different authority then the one spawning the node, in that case, the spawn variables for that specific synchronizer are simply ignored (other synchronizers with the same authority of the spawner will correctly synchronize variables on spawn). The SceneReplicationState class has been completly removed, since it was bloating the implementation, the state is now simply stored in the SceneReplicationInterface.
