I'm not sure what to make of this unit test failure: https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=4952636&view=ms.vss-test-web.build-test-results-tab&runId=23305012&resultId=100052&paneView=debug

Probably failing in: https://github.com/xamarin/xamarin-android/blob/7c5fab13329ee898fb1562f83576a7ca881f2881/src/Mono.Android/Android.Runtime/XmlPullParserReader.cs#L78-L83

This doesn't really make sense to me, as the XmlPullParserReader(IJavaObject) constructor doesn't call .GetNamespace(). There is a .GetFeature() invocation, though…

Tests are currently re-running. We'll see if this requires more mental energy.

I'm thinking this will be green now.

Context: https://github.com/dotnet/runtime/pull/55384
Context: https://github.com/dotnet/sdk/pull/18639

Updates:

  * Microsoft.Dotnet.Sdk.Internal: from 6.0.100-preview.7.21327.2 to 6.0.100-rc.1.21369.3
  * Microsoft.NET.ILLink.Tasks: from 6.0.100-preview.6.21322.1 to 6.0.100-preview.6.21366.2
  * Microsoft.NETCore.App.Ref: from 6.0.0-preview.7.21326.8 to 6.0.0-rc.1.21368.1

dotnet/runtime#55384 broke how .NET 6 interacts with
`AndroidClientHandler`.  Fix this by introducing a new
`Xamarin.Android.Net.AndroidMessageHandler` type for use on .NET 6,
and update the .NET 6 `AndroidClientHandler` to delegate to
`AndroidMessageHandler`.

`AndroidMessageHandler` doesn't exist on Legacy.

Update `.apkdesc` files:

  * `BuildReleaseArm64SimpleDotNet` is ~37KB smaller
  * `BuildReleaseArm64XFormsDotNet` is ~62KB larger.

Update `tests/api-compatibility/api-compat-exclude-attributes.txt`
so that `T:System.Runtime.CompilerServices.CompilerGeneratedAttribute`
is ignored.  `[CompilerGeneratedAttribute]` is emitted as part of
C# 3 "auto-props":

	public T Property { get; set; }

Converting this into a "real" property:

	T value;
	public T Property {
	    get => value;
	    set => this.value = value;
	}

results in the `_CheckApiCompatibility` target complaining about an
API break.  We don't care; ignore `[CompilerGeneratedAttribute]`.

Remove `$(SelfContained)` property: early on in .NET 5 (yes 5)
development, the Xamarin.Android SDK needed to specify
`$(SelfContained)` by default in order to produce `.apk` files.

After we became a proper workload, setting the value became
unnecessary.  It also didn't actually do anything because
dotnet/sdk overwrote the value.

Starting in dotnet/sdk#18639,
`Microsoft.NET.RuntimeIdentifierInference.targets` is now being
imported *after* a workload, which meant that dotnet/sdk no longer
overwrote our `$(SelfContained)` value, which broke things:

	error NETSDK1031: It is not supported to build or publish a self-contained application without specifying a RuntimeIdentifier. You must either specify a RuntimeIdentifier or set SelfContained to false.

We can simply remove `$(SelfContained)` now, and rely on
dotnet/sdk to set this value.

One part to add is about the removal of $(SelfContained):

Early on in .NET 5 (yes 5) development, the Xamarin.Android SDK needed to specify `$(SelfContained)` by default.

After we became a proper workload, setting the value became unnecessary. It also didn't actually do anything because the dotnet/sdk overwrote the value.

Due to `Microsoft.NET.RuntimeIdentifierInference.targets` now being imported *after* a workload, the default value of `$(SelfContained)` broke things:

    error NETSDK1031: It is not supported to build or publish a self-contained application without specifying a RuntimeIdentifier. You must either specify a RuntimeIdentifier or set SelfContained to false.

See: https://github.com/dotnet/sdk/pull/18639

We can simply remove `$(SelfContained)` now, and rely on the dotnet/sdk to set this value.
