Changes: dotnet/java-interop@48766c0...476bb5b

  * dotnet/java-interop@476bb5b7: [build] .NET 6 P7 Support (#869)
  * dotnet/java-interop@0028e32c: [build] set $(DisableImplicitNamespaceImports) by default (#859)

We don't actually *care* about dotnet/installer@9c463710 bump.
We care that the attempt to build PR #6234 fails to build:

	…/xamarin-android/src/Mono.Android/Mono.Android.targets(247,5): error : CompatApi command: /Users/builder/.nuget/packages/microsoft.dotnet.apicompat/5.0.0-beta.20181.7/tools/net472/Microsoft.DotNet.ApiCompat.exe "/Users/builder/azdo/_work/2/s/xamarin-android/tests/api-compatibility/reference/Mono.Android.dll" -i "/Users/builder/azdo/_work/2/s/xamarin-android/bin/Release/lib/xamarin.android/xbuild-frameworks/Microsoft.Android/net6.0" --allow-default-interface-methods --baseline "/Users/builder/azdo/_work/2/s/xamarin-android/tests/api-compatibility/acceptable-breakages-vReference.txt" --validate-baseline --exclude-attributes "/Users/builder/azdo/_work/2/s/xamarin-android/tests/api-compatibility/api-compat-exclude-attributes.txt"
	…/xamarin-android/src/Mono.Android/Mono.Android.targets(247,5): error : CheckApiCompatibility found nonacceptable Api breakages for ApiLevel: v12.0.
	…/xamarin-android/src/Mono.Android/Mono.Android.targets(247,5): error : Compat issues with assembly Mono.Android:
	…/xamarin-android/src/Mono.Android/Mono.Android.targets(247,5): error : TypesMustExist : Type 'Xamarin.Android.Net.AndroidMessageHandler' does not exist in the implementation but it does exist in the contract.
	…/xamarin-android/src/Mono.Android/Mono.Android.targets(247,5): error : Total Issues: 1

It fails to build because we `CheckApiCompatibility` expects the
`Xamarin.Android.Net.AndroidMessageHandler` type to exist, and it
doesn't exist, because it was added until… 1e5bfa3.
That's the primary thing we're after.  Everything else is fluff, and
the dotnet/runtime-related changes are not otherwise needed -- or
cared about -- on d16-11.
