NFC: nci: Support all destinations type when creating a connection
The current implementation limits nci_core_conn_create_req() to only manage NCI_DESTINATION_NFCEE. Add new parameters to nci_core_conn_create() to support all destination types described in the NCI specification. Because there are some parameters with variable size dynamic buffer allocation is needed.
