net/mlx5: support flow match with external Tx queue

For using external created Tx queues in RTE_FLOW_ITEM_TX_QUEUE,
this commit provides the map and unmap functions to convert the
external created SQ's devx ID to DPDK flow item Tx queue ID.

net/mlx5: enable DevX Tx queue creation

Verbs API does not support Infiniband device port number larger 255 by
design. To support more representors on a single Infiniband device DevX
API should be engaged.

While creating Send Queue (SQ) object with Verbs API, the PMD assigned
IB device port attribute and kernel created the default miss flows in
FDB domain, to redirect egress traffic from the queue being created to
representor appropriate peer (wire, HPF, VF or SF).

With DevX API there is no IB-device port attribute (it is merely kernel
one, DevX operates in PRM terms) and PMD must create default miss flows
in FDB explicitly. PMD did not provide this and using DevX API for
E-Switch configurations was disabled.

The default miss FDB flow matches E-Switch manager vport (to make sure
the source is some representor) and SQn (Send Queue number - device
internal queue index). The root flow table managed by kernel/firmware
and it does not support vport redirect action, we have to split the
default miss flow into two ones:

- flow with lowest priority in the root table that matches E-Switch
manager vport ID and jump to group 1.
- flow in group 1 that matches E-Switch manager vport ID and SQn and
forwards packet to peer vport

net/mlx5: separate Tx queue object creations

As an arrangement to Windows OS support, the Verbs operations should be
separated to another file.
By this way, the build can easily cut the unsupported Verbs APIs from
the compilation process.

Define operation structure and DevX module in addition to the existing
Linux Verbs module.
Separate Tx object creation into the Verbs/DevX modules and update the
operation structure according to the OS support and the user
configuration.

When updating a queue vlan stripping offload - either the WQ is modified
in Verbs or the RQ is modified in DevX. Add a vlan stripping modify
callback to 'struct mlx5_obj_ops' and assign it with the specific Verbs
and DevX implementations: 'rxq_obj_modify_wq_vlan_strip' and
'rxq_obj_modify_rq_vlan_strip' respectively.
