* Add test

* Fix the visitor

* Make sure the main branch is using .NET 8 SDK

The main branch needs to use the .NET 8 SDK because we are building the .NET 7 TFMs as well. The .NET 9 SDK does not support .NET 7 TFMs anymore.

* no previews!

Since we're moving in a different direction for moving these over in #22635 these projects (and the Issue11853 test, since it's in the other PR) can be deleted.

### Description of Change

We were recommending some now less than useful extensions. This updates
the recommended extensions to be: C# Dev Kit, C# Intellicode, and GitHub
CoPilot Chat, which will pull in their required dependencies as well.

### Description of Change

PopLifeCycle fails a small percentage of the time, but just enough to be
frustrating. I've tried a number of variations that always seem to
resolve but alas they do not.

This PR adds an assert into the bad code path so we can get a better
stack trace of the bad path that's firing

Since we're moving in a different direction for moving these over in
#22635 these projects (and the Issue11853 test, since it's in the other
PR) can be deleted.

Changes: dotnet/android@34.0.79...34.0.113

I noticed the Android workload version used in dotnet/maui/main was a couple service releases old.

We should use the latest one, as it has a memory leak fix for `Post()`.

### Description of Change

Merging!

Fixes: #21453
Context: #22810

In #22810, a leak in `NavigationPage` was fixed for the case:

    Application.Current.MainPage = new NavigationPage(new Page1());
    Application.Current.MainPage = new Page2();

However, it does *not* work for the case:

    await Navigation.PushModalAsync(new NavigationPage(new Page1()));
    await Navigation.PopModalAsync();

I could reproduce this problem in `MemoryTests.cs`.

There were still a few cycles in `NavigationRenderer`:

* `NavigationRenderer` -> `VisualElement _element` ->
`NavigationRenderer`

* `NavigationRenderer` -> `Page Current` -> `NavigationRenderer`

* `NavigationRenderer` -> `ViewHandlerDelegator<NavigationPage>
_viewHandlerWrapper` -> `TElement _element` -> `NavigationRenderer`

After fixing these cycles, the test passes. The customer's sample also
seems to work:

`ViewHandlerDelegator` was slightly tricky, as I had to make a
`_tempElement` variable and *unset* it immediately after use.

* [ios/catalyst] fix memory leak in TabbedPage

Context: #23164

Just the same way as `NavigationPage` in #23164, `TabbedPage` also has
a memory leak caused by the cycle:

* `TabbedPage` -> `TabbedRenderer` -> `VisualElement _element;` -> `TabbedPage

I could add a new `[Theory]` in `MemoryTests.cs` to see the issue.

This PR fixes the memory leak by breaking the cycle in `TabbedRenderer`.

* Ignore test on Windows

I also cleaned up the Task.Delay()
