feat: port to Godot 4

[yuna0x0]

Windows port is done and tested on my side.

Unix-based port is currently blocked by Abdera7mane/Godot-UnixSocket. Need to port it from GDNative to GDExtension.

The main branch's Unix code is blocked by the Godot-UnixSocket, which needs to port to GDExtension. It will not work currently.

I have opened a Windows branch which removes Unix-related code. If you want to test it out on Windows.

[Abdera7mane]

I have ported Abdera7mane/discord-rpc-gdscript@203f6d5 to Godot 4 and Abdera7mane/Godot-UnixSocket@9e3e106 to GDExtension however MacOS support is lacking.

I also took this as an opportunity to rework on the Discord RPC implementation and made it way simpler. Here is an example of rich presence update:

var discord := DiscordRPC.new()

# establish a connection and wait for rpc_ready signal

discord.update_presence({
  details = "In menu",
  state = "AFK",
  assets = {
    large_image = "icon"
  }
})

I still have some things to add before v2 release.

It would be nice to have this working again. I tested @edisonlee55 's branch and it seems to be working fine (aside from one parameter that needed to be removed) just for Windows, which is just enough for my use-case. Still would be nice to be able to download this from the AssetLib.
