Clarify effective validation attributes

[guardrex]

Description

We don't have a list, and telling readers to just look at the DA API (<xref:System.ComponentModel.DataAnnotations?displayProperty=fullName>) isn't sufficient to identify:

• The ones that only pertain to validation.
• The ones that will work with the DA Validator in Blazor.
• The ones that will work with a little extra code applied for client-side validation and perhaps an example implementation of that code (e.g., [CreditCard] might be the only one if the MVC validation article is correct).

I think we'll need to provide a list of the effective attributes for the article.

We already mention custom data annotation validation attributes and cross-link to the MVC article on that. However, I really have no idea on the gotchas 😈 and dragons 🐉 of trying to follow that guidance in a Blazor app with an EditForm and DataAnnotationsValidator. Maybe it works, or maybe it 💥 in your face 😨.
