[NET10] Switch to public MAUI types for AvatarView

[jfversluis]

For .NET 10 the InternalsVisibleTo has been removed for the .NET MAUI Community Toolkit (see here). I have made the types that we used for AvatarView public, so we need to switch to using those.

The rest of the types we are using will be removed with the Popup v2 PR and the last one can be removed with the alternative AppThemeResource implementation in #2639.

Thanks Gerald! Have you confirmed this for CommunityToolkit.Maui.Markup as well?

Can you point me in the direction of what to look at for AvatarView, as I'd like to understand it and if I can, make the appropriate changes. As I was the one who implement the MAUI version of AvatarView.

I note that it's been reverted? #29321

@GeorgeLeithead is reverted because we didn't make changes here, so if anyone tries MCT + .NET MAUI 10 it will break

Haha yeah, slip up on my side. I didn't think this through enough. The change was fine, but our tests started failing because the Toolkit side didn't make the necessary changes yet.

I've discussed it a bit more, and removing the InternalsVisibleTo is not a breaking change. So what I'll do is create a new PR that makes the necessary types public, the Toolkit can do the transition when we want, probably close to .NET 10 GA, and then I will remove the InternalsVisibleTo for a .NET 10 service release. That way tests will stay happy, we have a transition path and we still don't need to wait another full year to tidy this up :)

Here is the first PR: https://github.com/dotnet/maui/pull/29443

These should be the types that we will need to start using!
