`Java.Interop.__TypeRegistrations` isn't always removed

### Android application type

.NET Android (net7.0-android, etc.)

### Affected platform version

.NET 8

### Description

The `Java.Interop.__TypeRegistrations` type is (mostly) vestigial (except when using the Android Designer), and should never be used on-device. We should thus always remove it. We even have a unit test for that!

https://github.com/xamarin/xamarin-android/blob/a5fb6054a2bd5a79e7b7810d174f0d74135c2689/src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Tasks/LinkerTests.cs#L478-L479

(When `enabled` is true, `VSAndroidDesigner` is set, so `__TypeRegistrations` is preserved. Otherwise, it is removed by default.)

Yet…

### Steps to Reproduce

```sh
% dotnet new maui -n yay-maui
% cd yay-maui
% dotnet build -f net8.0-android -p:Configuration=Release
% for f in obj/Release/net8.0-android/android-arm64/linked/*.dll; do echo "## $f"; monodis --typedef $f | grep __TypeRegis ; done
…
## obj/Release/net8.0-android/android-arm64/linked/Microsoft.Maui.dll
11: Java.Interop.__TypeRegistrations (flist=1, mlist=34, flags=0x100000, extends=0x61)
584: Java.Interop.__TypeRegistrations/<>O (flist=931, mlist=3904, flags=0x100183, extends=0x61)
```

Why does `Microsoft.Maui.dll` have a `Java.Interop.__TypeRegistrations` type?! Nothing else does.
