ice: Report SR-IOV VF statusHEADmain

Report the VF MAC, allocated transmit and receive queues, exact trunk
VLAN-filter count and capacity, negotiated virtchnl API, configured MAC,
VLAN, spoof-check, and promiscuous-mode policy, automatic link-state
policy, PF traffic permission, and fault containment through iflib.

Expose mirror configuration and active hardware rules, precise
malicious-driver isolation and counters, software mailbox-overflow
isolation and counters, VF-owned MAC-filter count and limit, and reset
diagnostics through a versioned driver.ice extension.  Distinguish a
failed VF reset from a required VSI rebuild, which may still be pending
rather than failed.  Keep the namespace schema local to the driver so
future extensions need no changes to common network headers or the
formatter.

Invalidate cached VF handshakes during preparation for an externally
initiated device reset, before releasing the context lock to wait for
hardware.  Mark the VFs as requiring rebuild even if an early PF rebuild
failure prevents reaching their VSIs.  Software-initiated resets retain
their advance notification before invalidating the handshake.

The iflib context lock protects VF state and VSI lifetime while
constructing the snapshot.  The query uses only cached state and does
not issue AdminQ commands or read device registers.

Validation on E810 with host-attached iavf VFs used ifconfig -v and
direct Netlink queries to check handshake, queue, VLAN, policy, MDD,
and mailbox state across VF and PF resets.
