.NET MAUI `StackLayout` complicates migration from Xamarin.Forms

[jonathanpeppers]

Description

This issue is focused around many of the comments on https://github.com/dotnet/maui/issues/6317.

For example:

Frankly, I feel like StackLayouts are very confusing in MAUI and mostly useless, as we have to use Grid in most cases (StackLayout was confusing as hell in XF as well, but for different reasons). https://github.com/dotnet/maui/issues/6317#issuecomment-1247868641

Or another:

At least this change should be properly documented. Multiple issues were closed as "not-a-bug" (e.g. https://github.com/dotnet/maui/issues/5442, https://github.com/dotnet/maui/issues/4115, https://github.com/dotnet/maui/issues/4107, I assume that this one will be closed as well), and in all of them it was mentioned that this changed should be documented. But I haven't found any mentions of that neither in StackLayout documentation, nor in XF migration guide. https://github.com/dotnet/maui/issues/6317#issuecomment-1248178179

We have a doc focused on some of the layout differences:

/cc @davidbritch if you have some ideas on what we could add to official migration docs. Thanks!

Published yesterday: https://learn.microsoft.com/dotnet/maui/migration/layouts, so I guess this can be closed.

@PureWeen the new docs page looks good to me. Did you have an idea here besides docs?
