Bluetooth: controller: Redesign the implementation/use of NODE_RX_TYPE_DC_PDU_RELEASE

[cvinayak]

Is your enhancement proposal related to a problem? Please describe.
To release received on-air PDU that does not translate to a message to ULL, the type is changed and enqueued towards ULL. This implementation is spread across many places. Come up an optimized common code in control path to reduce this scattered handling.

@kruithofa @thoh-ot Do consider this during the LLCP work. I am assuming this issue could be not applicable too and be closed with the new LLCP.

Closing this as no work has been done in this regard for an year now.
