[maui] track workload versions with Maestro

Context: https://github.com/dotnet/arcade/blob/main/Documentation/Darc.md

MAUI is currently pushing nightly .NET 9 builds to the .NET 9.0.1xx SDK Maestro channel.

To set this up, I created a set of dependencies in the eng/Version.Details.xml:

<Dependency Name="Microsoft.Maui.Controls" Version="1" />
<Dependency Name="VS.Tools.Net.Core.SDK.Resolver" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />
<Dependency Name="Microsoft.NETCore.App.Ref" Version="1" CoherentParentDependency="VS.Tools.Net.Core.SDK.Resolver" />
<Dependency Name="Microsoft.NET.Workload.Emscripten.Current.Manifest-9.0.100.Transport" Version="1" CoherentParentDependency="Microsoft.NETCore.App.Ref" />
<Dependency Name="Microsoft.Android.Sdk.Windows" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />
<Dependency Name="Microsoft.MacCatalyst.Sdk.net9.0_17.2" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />
<Dependency Name="Microsoft.macOS.Sdk.net9.0_14.2" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />
<Dependency Name="Microsoft.iOS.Sdk.net9.0_17.2" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />
<Dependency Name="Microsoft.tvOS.Sdk.net9.0_17.2" Version="1" CoherentParentDependency="Microsoft.Maui.Controls" />

With Version="1" as just a placeholder, I updated to the latest build:

> darc update-dependencies --id 232243

Found at: https://maestro-prod.westus2.cloudapp.azure.com/3884/https:%2F%2Fgithub.com%2Fdotnet%2Fmaui/latest/graph

Or you can also lookup builds such as using a commit has from the dotnet/maui/net9.0 branch:

> darc get-build --repo dotnet/maui --commit cf76a629023c99557239464a278daec280d1f448
Repository:    https://github.com/dotnet/maui
Branch:        net9.0
Commit:        cf76a629023c99557239464a278daec280d1f448
Build Number:  9.0.0-preview.7.24368.8+azdo.9904060
Date Produced: 7/18/2024 1:47 PM
Build Link:    https://dev.azure.com/devdiv/DevDiv/_build/results?buildId=9904060
AzDO Build Id: 9904060
BAR Build Id:  232243
Released:      False
Channels:
- .NET 9.0.1xx SDK

Using the numbers now in Version.Details.xml, you could install the corresponding .NET SDK and workloads with:

VS.Tools.Net.Core.SDK.Resolver -> version of .NET SDK for dotnet-install.sh/ps1

Remaining versions can be mapped to a "rollback" file for workloads:

{
    "microsoft.net.sdk.android": "34.99.0-preview.7.346/9.0.0-preview.7",
    "microsoft.net.sdk.ios": "17.2.9714-net9-p6/9.0.0-preview.7",
    "microsoft.net.sdk.maccatalyst": "17.2.9714-net9-p6/9.0.0-preview.7",
    "microsoft.net.sdk.macos": "14.2.9714-net9-p6/9.0.0-preview.7",
    "microsoft.net.sdk.maui": "9.0.0-preview.7.24368.8/9.0.0-preview.7",
    "microsoft.net.sdk.tvos": "17.2.9714-net9-p6/9.0.0-preview.7",
    "microsoft.net.sdk.mono.toolchain.net9.0": "9.0.0-preview.7.24357.2/9.0.0-preview.7",
    "microsoft.net.sdk.mono.toolchain.current": "9.0.0-preview.7.24357.2/9.0.0-preview.7",
    "microsoft.net.sdk.mono.emscripten.net9.0": "9.0.0-preview.7.24319.4/9.0.0-preview.7",
    "microsoft.net.sdk.mono.emscripten.current": "9.0.0-preview.7.24319.4/9.0.0-preview.7"
}

Saved as workload.json you could run:

> dotnet workload install maui --from-rollback-file workload.json

If we had some script in place to use Version.Details.xml, we could then use Maestro to update it with a subscription such as:

darc add-subscription --channel ".NET 9.0.1xx SDK" --target-branch main --source-repo https://github.com/dotnet/maui --target-repo https://github.com/dotnet/performance

/cc @LoopedBard3 if this is a solution for MAUI-related scenarios.
