net8.0-android failed to build, assembly not found

### Tested versions

- Reproducible in: 4.3.stable.mono.official.77dcf97d8

### System information

Godot v4.3.stable.mono - Manjaro Linux #1 SMP PREEMPT_DYNAMIC Wed Aug 7 16:19:28 UTC 2024 - Wayland - GLES3 (Compatibility) - AMD Radeon Vega 3 Graphics (radeonsi, raven2, LLVM 18.1.8, DRM 3.57, 6.9.12-3-MANJARO) - AMD Ryzen 3 3250U with Radeon Graphics (4 Threads)

### Issue description

I am forced to use net8.0-android because I need to have SkiaSharp.NativeAssets.Android for APK.
When building APK, it emits this:

Though, if I use net8.0 it will be built. But libSkiaSharp dll won't be found (during using the application) [messages from logcat]

```

I expected from one of these, I can use SkiaSharp on Android.

### Steps to reproduce

1. Clone recursively: [GitHub](https://github.com/symful/kaolin.flow-godot-skiasharp)
2. Open the Godot project in the `scene/` folder
3. Export Android

You may change the `TargetFramework` in the folder to `net8.0`, compile it, then run in your phone to test it out for the second case I mentioned above.

### Minimal reproduction project (MRP)

https://github.com/symful/kaolin.flow-godot-skiasharp (not so minimal, but I don't have time to make one)

Start with the linked kaolin.flow-godot-skiasharp project, open the Godot project in the scene/ folder, and reproduce the Android export with TargetFramework set to net8.0-android. Compare it with the net8.0 build and its logcat output; done means the Android export succeeds and the application can load libSkiaSharp.
