Fix templates that use `<LibraryProjectZip>`

[jpobst]

Context: dotnet/maui#8233

We currently use <LibraryProjectZip> to specify which Java library we want to bind. Unfortunately, using this alone does not produce valid NuGet packages for .NET 6. These packages are missing the .jar/.aar library that should sit next to the .dll. (This library is no longer embedded in the .dll in .NET 6.)

We need to switch to using <AndroidLibrary> instead, which will do the correct thing for both .NET 6 and classic XA.

It looks like we use <LibraryProjectZip> in 22 templates:

Once changed, verify that the .aar is in the NuGet. ex:

This is likely causing many issues like:

• Xamarin.Google.MLKit.BarcodeScanning is not loading in Maui #630
• Xamarin.Firebase.Messaging crashing on failed resolution of datatransport/TransportFactory #604
• Failed resolution of: Lcom/google/android/datatransport/TransportFactory when using Xamarin.Firebase in MAUI #560
