TextColorToGenerator - Make access modifiers for generated classes for Maui Controls adjustable

[loop8ack]

This discussion is based on my question: #756
I have a solution for my project, but the real problem is still there.

I had the problem that the TextColorToGenerator always generates the code for Maui controls public, which causes conflicts with multiple projects.
Since I always set TreatWarningsAsErrors to true, I clearly noticed this (many CS0436 erros), others will see this as warnings.

<PropertyGroup>
    <CommunityToolkit_Maui_GeneratedCodeForMauiControlsPublic>true</CommunityToolkit_Maui_GeneratedCodeForMauiControlsPublic>
</PropertyGroup>

The purpose of this property is to be able to provide a simple solution in case of a problem with this change (public -> internal).
Accepted values are true (public) or false (internal), the default value would be empty (internal).
Or we change this setting so that the default value is public and can be changed to internal.

It would also be enough to always leave the access modifier internal (without setting), but that would be a breaking change, with no way to do anything about it.

What do you think?
