FFI v0.12.2 & RPC

[bcherry]

This PR upgrades the FFI version to the latest and includes the RPC feature.

I did not adopt the majority of FFI changes but my limited testing did not suggest they are breaking changes so I believe this is safe but @theomonnom and @cloudwebrtc would know for sure.

The only other blocking issue is that the latest FFI does not build for all runtimes, which will prevent us from releasing a new version of this SDK.

I verified this works for now but I'd love to get SDK version in. it's just not clear where to get it from at runtime? Might need to inject it into a script like we do for the node SDK. any ideas @cloudwebrtc @theomonnom ?

I found this but don't know if it works as expected
https://discussions.unity.com/t/how-get-packageinfo-by-name-and-version/762057/8

using UnityEngine;
using System.Linq;
using UnityEditor.PackageManager;

// ... within some class ...

private PackageInfo GetPackageInfo(string packageName)
{
    return UnityEditor.AssetDatabase.FindAssets("package")
        .Select(UnityEditor.AssetDatabase.GUIDToAssetPath)
            .Where(x => UnityEditor.AssetDatabase.LoadAssetAtPath<TextAsset>(x) != null)
        .Select(PackageInfo.FindForAssetPath)
            .Where(x => x != null)
        .First(x => x.name == packageName);
}

string packageName = "com.unity.cinemachine";
Debug.Log(GetPackageInfo(packageName).version);

From what I saw online, UnityEditor isn't available at runtime on-device, only when running from the Unity Editor? Do you think that's accurate?

[bcherry]

gonna just punt on this

[cloudwebrtc]

Yeah, you are right, maybe we can add a version.cs, but we must check that the version number in version.cs is consistent with package.json before releasing a new version

[bcherry]

in the node sdk we dynamically generate a version.js file as part of the build process, but i'm not sure there's a clean way to pull that off here.

[cloudwebrtc]

if the Unity build process can generate version.cs, I think it is a good idea.

lgtm!
