GDExtension

This GDExtension is just a wrapper around Discord Social SDK, which means that you call the GDExtension method and it calls the SDK method.

    gdscript[GDScript]
    gdextension[GDExtension]
    sdk[SDK]

    gdscript --"Discord.enum_to_string()"--> gdextension
    gdextension --discordpp::EnumToString()--> sdk

    sdk --"std::string"--> gdextension
    gdextension --"String"--> gdscript

Basically, this GDExtension job is convert between Godot variables and C++ variables.

For example, when you pass a String to a GDExtension method, it will convert to std::string before passing to the SDK method. And the opposite convertion needs to happen when returning from SDK.
