interconnect: core: Add dynamic id allocation support
The current interconnect framework relies on static IDs for node
creation and registration, which limits topologies with multiple
instances of the same interconnect provider. To address this,
introduce icc_node_create_dyn() and icc_link_nodes() APIs to
dynamically allocate IDs for interconnect nodes during creation
and link. This change removes the dependency on static IDs,
allowing multiple instances of the same hardware, such as EPSS L3.
