Merge branch 'net: struct netdev_rx_queue and xdp.h reshuffling'

Jakub Kicinski says:

====================
While poking at struct netdev_rx_queue I got annoyed by
the huge rebuild times. I split it out from netdevice.h
and then realized that it was the main reason we included
xdp.h in there. So I removed that dependency as well.

This gives us very pleasant build times for both xdp.h
and struct netdev_rx_queue changes.

I'm sending this for bpf-next because I think it'd be easiest
if it goes in there, and then bpf-next gets flushed soon after?
I can also make a branch on merge-base for net-next and bpf-next..

v2:
 - build fix
 - reorder some includes
v1: https://lore.kernel.org/all/20230802003246.2153774-1-kuba@kernel.org/
