Introduce XDP RX checksum capability to XDP metadata specs. XDP RX checksum will be use by devices capable of exposing receive checksum result via bpf_xdp_metadata_rx_checksum(). Moreover, introduce xmo_rx_checksum netdev callback in order allow the eBPF program bounded to the device to retrieve the RX checksum result computed by the hw NIC.
