  1. [Microsoft.Android.Sdk.ILLink] target net7.0 temporarily

    Context: xamarin/xamarin-macios#17560
    Context: dotnet/runtime#82241
    
    On macOS, if you have both .NET 7 and .NET 8 Preview 1 installed, and
    you do:
    
    * `dotnet new android`
    
    * `dotnet build -c Release`
    
    You get a build error:
    
        Fatal error in IL Linker
        Unhandled exception. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
        ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

            at Mono.Linker.Driver.Main(String[] args)
    
    This happens because the linker is actually trying to run against the
    .NET 7 runtime! It promptly blows up against `net8.0` linker steps.
    
    Trying the same workaround as xamarin-macios, to build our linker steps
    for `net7.0`
