Improve Spinner parameter docs and metadata (#1228)

Enhanced XML comments for Spinner parameters using <see cref="..."/> and <para> tags for clarity. Added [AddedVersion], [DefaultValue], and [Description] attributes to all parameters for better tooling support. Changed VisuallyHiddenText from nullable string to non-nullable string. Improves API documentation and developer experience.
