feat: implement Asset specialization (eclipse-edc#4297)

* add isCatalog() method to Asset * api ingress: handle edc:CatalogAsset * change dcat:Catalog -> edc:CatalogAsset * api egress: handle edc:CatalogAsset * store isCatalog in the properties map * add boolean equality operator predicate

 The following changes will be made:
 
 - A boolean subtype field will be introduced on `Asset` to indicate if it is a catalog. This field will be set to `true`
-  when an optional `@type` property is set to `dcat:Catalog` when an asset is created in the Management API.
+  when an optional `@type` property is set to `edc:CatalogAsset` when an asset is created in the Management API.
 - The Management API will be updated in a backward-compatible way to handle optionally specifying the `@type` property

 - `Catalog` will extend `Dataset`.
