Component: Event Sourcing Attributes

[JoshuaEstes]

To make things easier, implement attributes to configure aggregates.

Example:

#[Aggregate]
class User
{
  #[AggregateId]
  private AggregateIdInterface $aggregateId;

  #[AggregateVersion]
  private AggregateVersionInterface $aggregateVersion;

  #[ApplyEvent(event: Updated::class)]
  public function applyUpdated(Updated $event): void {}
}

The ApplyEvent can be added to any method. Other attributes could include: Repository (or could be part of the Aggregate attribute), Upsert, and maybe a few others.
