Use MOXY for ITwAttributeComponent and implementation

[StevenTCramer]

We curently have IAttributeComponent and the base component implementing it.

public class BaseComponent :  IAttributeComponent
{
[Parameter(CaptureUnmatchedValues = true)]
public IReadOnlyDictionary<string, object> Attributes { get; set; } = new Dictionary<string, object>();
}

This could easily be done with a an attribute and Moxy.

Would be nice to add those to TimeWarp-SourceGen library.
