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

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".

Fabio Alessandrelli 33dda2e68a [MP] Remove connection state signals from MultiplayerPeer.
Now handled directly by the MultiplayerAPI implementation.

Fabio Alessandrelli 39f3d9d59e [MP] Add MultiplayerPeer disconnect_peer, close.
Update ENet, WebRTC, and WebSocket to support peer disconnection and
unify the close function.

Fabio Alessandrelli 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.

Fabio Alessandrelli ca7d572908 [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.

reduz 746dddc067 Replace most uses of Map by HashMap
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
  (order matters) but use is discouraged.

There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!

Rémi Verschelde 1769f80547 WebRTC: Fix potential nullptr dereference in error message
This was evidently a typo. Didn't get a crash but GCC 12 raised a
`-Warray-bounds` warning:

Fabio Alessandrelli 84112d9610 [Net] Fix WebRTC returning packets from peers too early.
Due to the async nature of WebRTC implementations, the multiplayer peer
could end up having queued packets from a given connection before it is
able to emit the "peer_added" signal.
This commit ensures that packets from peers which are not notified yet
are skipped by `get_packet` and `get_available_packet_count`.

Fabio Alessandrelli bf9aae09ba [Net] Move multiplayer to core subdir, split RPCManager.
Move multiplayer classes to "core/multiplayer" subdir.

Move the RPCConfig and enums (TransferMode, RPCMode) to a separate
file (multiplayer.h), and bind them to the global namespace.

Move the RPC handling code to its own class (RPCManager).

Renames "get_rpc_sender_id" to "get_remote_sender_id".

reduz 6631f66c2a Optimize StringName usage
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.

This is part of ongoing work to optimize GUI and the editor.
