devlink: Fix reload stats structure

BugLink: https://bugs.launchpad.net/bugs/1962490

Fix reload stats structure exposed to the user. Change stats structure
hierarchy to have the reload action as a parent of the stat entry and
then stat entry includes value per limit. This will also help to avoid
string concatenation on iproute2 output.

Reload stats structure before this fix:
"stats": {
    "reload": {
        "driver_reinit": 2,
        "fw_activate": 1,
        "fw_activate_no_reset": 0
     }
}

After this fix:
"stats": {
    "reload": {
        "driver_reinit": {
            "unspecified": 2
        },
        "fw_activate": {
            "unspecified": 1,
            "no_reset": 0
        }
}

UBUNTU: SAUCE: bpf: Add a helper to issue timestamp cookies in XDP

BugLink: https://bugs.launchpad.net/bugs/1934499

The new helper bpf_tcp_raw_gen_tscookie allows an XDP program to
generate timestamp cookies (to be used together with SYN cookies) which
encode different options set by the client in the SYN packet: SACK
support, ECN support, window scale. These options are encoded in lower
bits of the timestamp, which will be returned by the client in a
subsequent ACK packet. The format is the same used by synproxy.
