Reduce and prevent unnecessary random-access to List
Random-access access to `List` when iterating is `O(n^2)` (`O(n)` when
accessing a single element)

* Removed subscript operator, in favor of a more explicit `get`
* Added conversion from `Iterator` to `ConstIterator`
* Remade existing operations into other solutions when applicable

89dacb88ec [MP] Fix remote net ID cleanup
Synchronizers for spawned nodes were not correctly keeping track of the
net ID assigned by the remote, preventing the replication from
performing the proper cleanup.

This resulted in errors being thrown when sync messages were received
after despawn (which is possible due to their unreliable nature).

cb08f2a968 [MP] Fix spawned nodes not working after reset
Ensures that spawnable nodes (i.e. spawned nodes over which the local
instance has authority) always have a network ID, since they may lose it
after the multiplayer is reset (e.g. when changing the multiplayer peer).

9ce423914e [MP] Optimize internal authority checks
We already know which MultiplayerAPI a certain Node uses, so we don't
need to retrieve it via SceneTree every time.

522bddf63d [MP] Add a "synchronized" signal to MultiplayerSynchronized.

state.

2eadbe7b78 Fix multiplayer replication crash in on_sync_receive.
A number of early continue cases applied the packet-provided `size`
without validation, allowing large uint32_t values to be treated as
negative offsets and leading to segfaults.

Now, we validate `size` against the buffer length immediately to avoid a
crash.

This could be triggered by receiving sync data for a synchronizer who's
root node had just been removed, since the code path that checked for
unusable sync state failed to advance the offset. Thus the next read
could interpret part of the payload as such an invalid `size`.

Now, we properly advance the read offset in that case (and raise a
better error).

ad3a4214c5 [MP] Fix nested spawning during "ready".
We want our spawns to be notified after ready, but we need to notify
them in the order they entered tree, so that nested spawners can be used
during "ready" (instead of having to await a frame).

One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

fdc4e73a2c [MP] RPC visibility.
Implemented using MultiplayerSynchronizers.

If you didn't use the synchronizer visibility features, nothing changes.

If you were using visibility, RPCs to broadcast should now behave as
expected in most configurations (i.e. by sending the RPC to _visible_
peers).

If you want to limit the visibility of RPCs for a node, add a
synchronizer for it, and configure the visibility via
"set_visibility_for" or by adding a visibility filter.

Style: Misc docs and comment style and language fixes
- Removed empty paragraphs in XML.
- Consistently use bold style for "Example:", on a new line.
- Fix usage of `[code]` when hyperlinks could be used (`[member]`, `[constant]`).
- Fix invalid usage of backticks for inline code in BBCode.
- Fix some American/British English spelling inconsistencies.
- Other minor fixes spotted along the way, including typo fixes with codespell.
- Don't specify `@GlobalScope` for `enum` and `constant`.

7536d15fe3 [MP] Let MultiplayerAPI handle packet relaying and peer signaling.
MultiplayerPeer changes:

- Adds is_server_relay_supported virtual method

Informs the upper MultiplayerAPI layer if it can signal peers connected
to the server to other clients, and perform packet relaying among them.

- Adds get_packet_channel and get_packet_mode virtual methods

Allows the MultiplayerAPI to retrieve the channel and transfer modes to
use when relaying the last received packet.

SceneMultiplayerPeer changes:

- Implement peer signaling and packet relaying when the MultiplayerPeer
  advertise they are supported.

ENet, WebRTC, WebSocket changes:

- Removed custom code for relaying from WebSocket and ENet, and let it
  be handled by the upper layer.
- Update WebRTC to split create_client, create_server, and create_mesh,
  with the latter behaving like the old initialize with
  "server_compatibility = false", and the first two supporting the upper
  layer relaying protocol.

32a62af648 [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.
