Additional information

This PR also adds <DisableTextColorToGenerator>true</DisableTextColorToGenerator> which provides the functionality to disable TextColorToGenerator inside a csproj.

I've added <DisableTextColorToGenerator>true</DisableTextColorToGenerator> to CommunityToolit.Maui.csproj, CommunityToolkit.Maui.Camera.csproj and CommunityToolkit.Maui.MediaElement.csproj because the TextColorToGenerator only needs to run for projects that add the NuGet Package CommunityToolkit.Maui; it does not need to generate any code inside the aforementioned projects.

The TextColorToSourceGenerator had to be disabled for CommunityToolkit.Maui.Camera.csproj and CommunityToolkit.Maui.MediaElement.csproj because it references CommunityToolkit.Maui.Core which these two projects do not.

The TextColorToSourceGenerator had to be disabled for CommunityToolkit.Maui.csproj because CommunityToolkit.Maui.UnitTests generates TextColorTo() extension methods and the compiler failed to build CommunityToolkit.Maui.UnitTests due to duplicate TextColorTo() methods generated by both CommunityToolkit.Maui and CommunityToolkit.Maui.UnitTests.
