Regression in .NET Framework Microsoft.CSharp.RuntimeBinder.Binder.Convert for dynamic type

### Describe the bug
With previous .NET Sdks it used to be possible to target net48 and consume a COM library, without going through hoops.
Now, a simple csproj straight up fails to compile with `CS0656` for `Microsoft.CSharp.RuntimeBinder.Binder.Convert`.

### To Reproduce
When building with `dotnet build /restore` you'll encounter a CS0656.
[ClassLibrary2.zip](https://github.com/user-attachments/files/17831410/ClassLibrary2.zip)
Regardless of Sdk specified in global.json

Repro Code

```
[ComImport]
[Guid("F7280EAD-C910-42CE-BC19-2E6D4113AB33")]
public interface ITest
{
dynamic VoidTest();
}

public class Class1
{
public static byte[] B(ITest test)
{
return (byte[])test.VoidTest(); // CS0656
}
}
```

### Exceptions (if any)
```
error CS0656: Missing member "Microsoft.CSharp.RuntimeBinder.Binder.Convert"
```

This worked previously, but installing 8.0.404 or 8.0.307 fails the same way now that .NET 9 is installed - it used to work previously.
