Get rid of `ParentDialog` in component dialogs

[atlass-dev]

Hi! I'm just curious if is it possible to remove usage of the ParentDialog literal in component dialogs like it's implemented in MudBlazor's dialogs: [CascadingParameter] MudDialogInstance MudDialog { get; set; } I assume it will make a code less bulky a little bit.

Thank you for your product, it's very helpful!
