Microsoft.Android.Sdk.Aot.targets

.NET 6 AOT support. You can find "legacy" Xamarin.Android AOT support
in Xamarin.Android.Legacy.targets.

For <MonoAOTCompiler/> usage, see:
* https://github.com/dotnet/runtime/blob/15dec9a2aa5a4236d6ba70de2e9c146867b9d2e0/src/tasks/AotCompilerTask/MonoAOTCompiler.cs
* https://github.com/dotnet/runtime/blob/15dec9a2aa5a4236d6ba70de2e9c146867b9d2e0/src/mono/netcore/nuget/Microsoft.NET.Runtime.MonoAOTCompiler.Task/README.md

These targets are running within the _ComputeFilesToPublishForRuntimeIdentifiers target.
They run in a context of an inner build with a single $(RuntimeIdentifier).

    NOTE: currently, the only way to allow $(AotAssemblies) in
    .csproj files is to import these in the Android workload
    when $(MonoAOTCompilerTasksAssemblyPath) is blank:
