Take into account xamarin.*.csharp.targets when finding location …

… for inserting framework specific props/targets.

E.g. the following NuGet packages generate target framework specific properties.

framework: monoandroid70

source https://nuget.org/api/v2

nuget Xamarin.Android.Support.v4 == 25.3.1
nuget Xamarin.Android.Support.v7.RecyclerView == 25.3.1
nuget Xamarin.Android.Support.Design == 25.3.1
nuget Xamarin.Android.Support.v7.CardView == 25.3.1

<Choose>
    <When Condition="$(TargetFrameworkIdentifier) == 'MonoAndroid' And ($(TargetFrameworkVersion) == 'v1.0' Or $(TargetFrameworkVersion) == 'v2.2' Or $(TargetFrameworkVersion) == 'v2.3' Or $(TargetFrameworkVersion) == 'v4.0.3' Or $(TargetFrameworkVersion) == 'v4.1' Or $(TargetFrameworkVersion) == 'v4.2' Or $(TargetFrameworkVersion) == 'v4.3' Or $(TargetFrameworkVersion) == 'v4.4' Or $(TargetFrameworkVersion) == 'v4.4W' Or $(TargetFrameworkVersion) == 'v5.0' Or $(TargetFrameworkVersion) == 'v5.1' Or $(TargetFrameworkVersion) == 'v6.0' Or $(TargetFrameworkVersion) == 'v7.0' Or $(TargetFrameworkVersion) == 'v7.1')">
      <PropertyGroup

If not placed after the import of Xamarin.Android.CSharp.targets those properties won't be defined resulting in a broken build.

Not quite sure if or where to add tests for those, any hints appreciated!

Is there a more general solution to this problem? I don't think it is good to list the world here...
