…reference assemblies The updated reference assemblies in Mono 5.0 don't depend on Microsoft.Build.Engine.dll anymore which contained the Microsoft.Build.BuildEngine namespace so this using isn't found anymore. It was unnecessary anyway so remove it.

…e using (dotnet#567) The updated reference assemblies in Mono 5.0 don't depend on `Microsoft.Build.Engine.dll` anymore, and that assembly contained the `Microsoft.Build.BuildEngine` namespace. Consequently, `ProjectBuilder.cs` doesn't build when using the updated Mono 5.0 reference assemblies. Remove the `using Microsoft.Build.BuildEngine` declaration, as it is unnecessary. (cherry-picked from 634ba1d)

However, they were still emitted, resulting in CS0628 warnings when compiling `Mono.Android.dll`. We consider changing `[Obsolete]` to `[Obsolete(error:true)]` to be acceptable because this is being done to `const` fields, so this won't break ABI, as there are no IL references to `const` fields, and because (1) there are "replacement" members which can be used, and (2) these fields have been obsolete for *years*. The "problem" here is that `Microsoft.DotNet.ApiCompat.exe`, which the `<CheckApiCompatibility/>` task uses from `src/Mono.Android/Mono.Android.targets`, sees every such change as an API break. This in and of itself is plausibly sensible, but the error message *itself* is bananas, e.g.: namespace Android.AccessibilityServices { public abstract partial class AccessibilityService : Android.App.Service { [Register ("GESTURE_SWIPE_DOWN", ApiSince = 16)] [Obsolete ("This constant will be removed in the future version. Use Android.AccessibilityServices.AccessibilityGesture enum directly instead of this field.", error: true)] public const Android.AccessibilityServices.AccessibilityGesture GestureSwipeDown = (Android.AccessibilityServices.AccessibilityGesture) 2; } } results in: CannotRemoveAttribute : Attribute 'System.ObsoleteAttribute' exists on 'Android.AccessibilityServices.AccessibilityGesture Android.AccessibilityServices.AccessibilityService.GestureSwipeDown' in the contract but not the implementation. The message implies that `[Obsolete]` was removed, which isn't strictly true! `[Obsolete]` is still there! It's just that the constructor parameters have changed. This results in a ginormous change to `tests/api-compatibility/acceptable-breakages-vReference.txt`. The "`protected` members within `sealed` types" fix for CS0628 also resulted in errors from the Tests > API Compatibility job, which runs via `external/xamarin-android-api-compatibility`. Given that commit 07e7477 was intended to *replace* the Tests > API Compatibility job, *remove* the `external/xamarin-android-api-compatibility` submodule reference. We will no longer be using that submodule for API compat checks. Co-authored-by: Jonathan Pobst <monkey@jpobst.com>
