[build] Create Microsoft.iOS.Windows.Sdk workload pack (#11251)

Converts the Microsoft.iOS.Windows.Sdk NuGet package into a proper [workload SDK pack][0]. The entry point for this pack has been changed, and it is now imported through the `WorkloadManifest.targets` file included in `Microsoft.NET.Workload.iOS`, rather than being imported directly from `Microsoft.iOS.Sdk`. Import ordering has otherwise changed slightly. The following files are now imported before the majority of the `Microsoft.iOS.Sdk` (and the majority of the .NET SDK targets): * Xamarin.iOS.Common.Before.props * Xamarin.iOS.Common.Before.targets After this the majority of the .NET SDK targets will load, followed by the `Microsoft.iOS.Sdk` targets. Finally, everything declared in the `<AfterMicrosoftNETSdkTargets/>` hook loads, which consists of: * Microsoft.iOS.Windows.Sdk.targets * tools/msbuild/* [0]: https://github.com/dotnet/designs/blob/main/accepted/2020/workloads/workload-manifest.md#sdk-packs Co-authored-by: Rolf Bjarne Kvinge <rolf@xamarin.com>
