net: page_pool: expose page pool stats via netlink
Dump the stats into netlink. More clever approaches
like dumping the stats per-CPU for each CPU individually
to see where the packets get consumed can be implemented
in the future.
A trimmed example from a real (but recently booted system):
$ ./cli.py --no-schema --spec netlink/specs/netdev.yaml \
--dump page-pool-stats-get
