Create a new Microsoft.NET.Sdk.Maui .NET SDK

[mattleibow]

Description of Change

This allows for some more complex operations where we can have the project SDK and use NuGet packages without needing to have the .NET MAUI workload installed.

I have a test here: https://github.com/mattleibow/Microsoft.NET.Sdk.Maui

This change is optional but will allow for a project to look like this if the workload is NOT installed:

<Project Sdk="Microsoft.NET.Sdk.Maui/8.0.0">
    <!-- no need for UseMaui -->
</Project>

One downside is that may be a blocking action as the SDK will have to download or validate the package is downloaded on each evaluation. I will need to verify this.

However, if the workload IS installed, then we do not get any additional cost and the workload behaves like all the others - and we can leave off the version number:

<Project Sdk="Microsoft.NET.Sdk.Maui">
    <!-- no need for UseMaui -->
</Project>

Tasks

• Create normal SDK Microsoft.NET.Sdk.Maui
• Create Blazor/Razor SDK Microsoft.NET.Sdk.Maui.Razor

This is the magic that makes things work - no version here as we are using the workload version.

Closing this for now. The better fixes are to make sure the various platforms work better with NuGet packages - mostly WinUI is causing trouble.
