Assert failing when trimming Maui Android app

### Repro steps

1. Install Maui, or build it from source: https://github.com/dotnet/maui/blob/main/.github/DEVELOPMENT.md (ping @eerhardt if you are going to set it up yourself. It is currently a little hard to set up.)
2. `dotnet new maui`
3. `dotnet restore`
4. `dotnet build -f net6.0-android -r android-arm64 -c Release --no-restore /bl`
5. Look at the command line passed to `$task illink`, and use that command line with a `Debug` built linker.
6. Running the Debug linker with the same command line hits assertions here:
