Model's morph mapped names using PHP8 attributes

[walirazzaq]

Currently to define morphMap for models we have Relation::morphMap method which we normally call from ServiceProviders.
I was wondering if we can use PHP8 attributes on model class itself to define morph mapped name

#[MorphMap('user')]
class User extends Model
{
   //...
}

We can further introduce artisan commands to generate and cache morphMap for larger applications having quite a few models
