~~ Changes to the build ~~

`$(DotNetTargetFrameworkVersion)` is `9.0`, making assemblies like
`Mono.Android.dll` target .NET 9.0, as well as `$(TargetFramework)`
in project templates, etc.

`$(DotNetStableTargetFramework)` is `8.0`, making various bootstrap
tooling, command-line tools, and unit tests target .NET 8.0.

.NET 9 has a new `.binlog` format, requiring
`MSBuild.StructuredLogger` 2.2.100.

`System.CodeDom` now targets 8.0.0, as we moved to 17.8 MSBuild
assemblies from `xamarin-android-tools`.

Add the `dotnet9` and `dotnet9-transport` feeds. The
`dotnet9-transport` feed is used for non-customer-facing packages
like `Microsoft.NET.ILLink`.

`build-linux.yaml` was initially failing to restore `net8.0`
projects because of the order it installed a .NET SDK. It was only
working for `net7.0` projects, because a .NET 7 SDK was
preinstalled on the build machines.

Update `TestSlicerToolVersion` and `dotnet-test-slicer` to
`0.1.0-alpha7`, previously it was failing to discover tests in a
`net8.0` project.

Provision Mono workload manifests for: `net6`, `net7`, `net8`, and
`current` (`net9`).  Call `Utilities.DeleteDirectory()` on these
directories to be sure we are in a clean state.

dotnet/android-tools@21de3d7 is needed to fix various
NU1605 warnings:

	error NU1605: Warning As Error: Detected package downgrade: Microsoft.Build.Framework from 17.5.0 to 17.3.2. Reference the package directly from the project to select a different version.
	error NU1605:  MSBuildDeviceIntegration -> MSBuild.StructuredLogger 2.2.100 -> doh (>= 17.5.0)
	error NU1605:  MSBuildDeviceIntegration -> Microsoft.Build.Framework (>= 17.3.2)

Update workload aliases to include `Microsoft.Android.Sdk.net9` and
`Microsoft.Android.Sdk.net8`.

Remove the .NET 7 Android workload from .NET 9.
Import `Eol.targets` for .NET 6/7 projects.

Update various parameterized tests to target `net8.0` and `net9.0`
appropriately while dropping `net7.0` support.

An initial update to the AOT profile for .NET 9.

Updated `*.apkdesc` files: there were some minor `.apk`
size changes.


~~ `$(AllowSelfContainedWithoutRuntimeIdentifier)` ~~

Context: dotnet/sdk@d21e6bf
Context: d12da3a

@rolfbjarne introduced an "escape hatch" in the .NET 9 SDK for emitting
a build warning for a case that doesn't make sense on mobile.
All mobile apps are self-contained, and we define RIDs by default, so
the error is not needed.

We can also stop setting `$(PublishSelfContained)` to `false`, as
`$(AllowSelfContainedWithoutRuntimeIdentifier)` is sufficient in .NET 9.


~~ Changes to `<ILStrip/>` ~~

Context: dotnet/runtime#90436

  * `$(IntermediateOutputPath)` is now required.

  * `[Output] TrimmedAssemblies` renamed to `UpdatedAssemblies`.

  * Output items shape changed, so now use
    `%(UntrimmedAssemblyFilePath)` and we can `<Copy/>` based on
    `%(ILStripped)`.

The new code is better, so generally these changes seem *good*.


~~ Refactoring ~~

Rename `$(AndroidNet7Version)` to `$(AndroidNetPreviousVersion)` to make
this property more generic for future releases.

Use `@NET_PREVIOUS_VERSION@` as a replacement instead of `@NET7_VERSION@`.


~~ TODO ~~

  * #8548

    The `MicrosoftIntune` test is failing because they have a check for
    == `8.0` that needs to be updated to be >= `8.0`.  This test is
    running on our `release/8.0.1xx` branch, but we can hopefully
    re-enable in main after their next release.

  * A specific case of `dotnet publish -f net8.0-android -r android-arm`
    is failing with:

        error NETSDK1185: The Runtime Pack for FrameworkReference 'Microsoft.Android.Runtime.34.android-arm' was not available. This may be because DisableTransitiveFrameworkReferenceDownloads was set to true.

    This is related to `$(AllowSelfContainedWithoutRuntimeIdentifier)`,
    but I will address in a future PR.  This will likely require .NET 8
    Android workload changes.
