This patch adds support for fdb_def_rule_en device argument to HW
Steering, which controls:
- the creation of the default FDB jump flow rule.
- the ability of the user to create transfer flow rules in the root
table.

This commit adds the support of connection tracking to HW steering as
SW steering did before.
The difference from SW steering implementation is that it takes
advantage of HW steering bulk action allocation support, in HW
steering only one single CT pool is needed.
An indexed pool is introduced to record allocated actions from bulk and
CT action state etc. Once one CT action is allocated from bulk, one
indexed object will also be allocated from the indexed pool, similar to
deallocating. That makes mlx5_aso_ct_action can also be managed by that
indexed pool, no need to be reserved from mlx5_aso_ct_pool. The single
CT pool is also saved to mlx5_aso_ct_action struct directly.
The ASO operation functions are shared with SW steering implementation.

This commit adds HW steering counter action support.
The pool mechanism is the basic data structure for the HW steering
counter.
The HW steering's counter pool is based on the rte_ring of zero-copy
variation.
There are two global rte_rings:
1. free_list:
Store the counters indexes, which are ready for use.
2. wait_reset_list:
Store the counters indexes, which are just freed from the user and
need to query the hardware counter to get the reset value before
this counter can be reused again.
The counter pool also supports cache per HW steering's queues, which are
also based on the rte_ring of zero-copy variation.
The cache can be configured in size, preload, threshold, and fetch size,
they are all exposed via device args.
The main operations of the counter pool are as follows:
- Get one counter from the pool:
1. The user call _get_* API.
2. If the cache is enabled, dequeue one counter index from the local
cache:
2. A: if the dequeued one from the local cache is still in reset
status (counter's query_gen_when_free is equal to pool's query
gen):
I. Flush all counters in the local cache back to global
wait_reset_list.
II. Fetch _fetch_sz_ counters into the cache from the global
free list.
III. Fetch one counter from the cache.
3. If the cache is empty, fetch _fetch_sz_ counters from the global
free list into the cache and fetch one counter from the cache.
- Free one counter into the pool:
1. The user calls _put_* API.
2. Put the counter into the local cache.
3. If the local cache is full:
A: Write back all counters above _threshold_ into the global
wait_reset_list.
B: Also, write back this counter into the global wait_reset_list.
When the local cache is disabled, _get_/_put_ cache directly from/into
global list.

This patch implements creating and caching of port action for use with
HW Steering FDB flows.
Actions are created on flow template API configuration and created
only on the port designated as the master. Attaching and detaching ports
in the same switching domain causes an update to the port actions cache
by, respectively, creating and destroying actions.
A new devarg fdb_def_rule_en is being added and it's used to control
the default dedicated E-Switch rules that are created by the PMD
implicitly or not, and PMD sets this value to 1 by default.
If set to 0, the default E-Switch rule will not be created and the user
can create the specific E-Switch rules on the root table if needed.

This patch introduces support for modify_field rte_flow actions in HWS
mode that includes:
- Ingress and egress domains,
- SET and ADD operations,
- usage of arbitrary bit offsets and widths for packet and metadata
fields.
This is implemented in two phases:
1. On flow table creation the hardware commands are generated, based
on rte_flow action templates, and stored alongside action template.
2. On flow rule creation/queueing the hardware commands are updated with
values provided by the user. Any masks over immediate values, provided
in action templates, are applied to these values before enqueueing rules
for creation.

Definers are HW objects that are used for matching, rte items
are translated to definers, each definer holds the fields and
bit-masks used for HW flow matching. The definer layer is used
for finding the most efficient definer for each set of items.
In addition to definer creation we also calculate the field
copy (fc) array used for efficient items to WQE conversion.

and the data processing thread may already be started, e.g: SPDK
vhost-blk and vhost-scsi will start the data processing thread
when one vring is ready, then deadlock may happen when SPDK is
posting interrupts to VM. Here, we add a new API which allows
caller to try again later for this case.
