Temporary validation control

[listepo]

I think it would be nice to have something like that CommunityToolkit/WindowsCommunityToolkit#3862,

[bijington]

@listepo we provide a set of validators that can be attached to controls see here for example: https://docs.microsoft.com/en-gb/dotnet/communitytoolkit/maui/behaviors/text-validation-behavior

The approach is slightly different to your link but I think it should satisfy most use cases. Do you think see other use cases?
