net/sfc: turn MAE flow action rules into shareable resources

Later patches of the series provide support for HW conntrack
assistance. With the new feature, multiple flows that differ
in the 5-tuple match fields but are otherwise identical will
be able to share all FW-allocatable objects except for those
of the conntrack table. That will boost flow engine capacity.

To prepare for that, action rules of the match-action engine
have to be turned into shareable objects, from SW standpoint.

net/sfc: rework flow action RSS support

Currently, the driver always allocates a dedicated NIC RSS context
for every separate flow rule with action RSS, which is not optimal.

First of all, multiple rules which have the same RSS specification
can share a context since filters in the hardware operate this way.

Secondly, entries in a context's indirection table are not precise
queue IDs but offsets with regard to the base queue ID of a filter.
This way, for example, queue arrays "0, 1, 2" and "3, 4, 5" in two
otherwise identical RSS specifications allow the driver to use the
same context since they both yield the same table of queue offsets.

Rework flow action RSS support in order to use these optimisations.

net/sfc: support jump flows in tunnel offload

JUMP is an in-house term for so-called "tunnel_set" flows. On parsing,
they are identified by virtue of actions MARK (PMD-internal) and JUMP.
The action MARK associates a given flow with its tunnel context.

Such a flow is represented by a MAE outer rule (OR) which has its
recirculation ID set. This ID is also associated with the tunnel
context. The OR is supposed to set this ID in 8 high bits of
Rx mark in matching packets. It also counts the packets.

Packets that hit the OR but miss in action rule (AR) table,
should go to MAE admin PF (that is, to DPDK) by default.

Support for the use of action COUNT in JUMP
flows will be introduced by later patches.
