Alerts do not display from ctor or OnAppearing when not in a NavPage/Shell

[mattleibow]

Description

Seems that the alerts are fired correctly and then added to the _pendingActions. However, the FlushPendingActions method only fires when the NavigatedTo even is invoked - and this only happens when in a nav page or in shell.

Steps to Reproduce

1. In the sandbox app
2. Use this code in the MauiProgram.cs:

	class App : Application
	{
		protected override Window CreateWindow(IActivationState activationState) =>
			new Window(new MainPage());
	}

3. Use this code in the MainPage.xaml.cs:

	protected override void OnAppearing()
	{
		base.OnAppearing();
		DisplayAlert("A", "B", "C");
	}

@PureWeen not sure the overall navigation / alerts plan, but saw this while trying to create tests for #12910
