net/iavf: use vector SW ring for all vector paths

The AVX-512 code path used a smaller SW ring structure only containing
the mbuf pointer, but no other fields. The other fields are only used in
the scalar code path, so update all vector driver code paths (AVX2, SSE)
to use the smaller, faster structure.

net/iavf: use common Tx queue mbuf cleanup

Adjust iavf driver to also use the common mbuf freeing functions on Tx
queue release/cleanup. The implementation is complicated a little by the
need to integrate the additional "has_ctx" parameter for the iavf code,
but changes in other drivers are minimal - just a constant "false"
parameter.

net/iavf: use common Tx free for AVX-512

Switch the iavf driver to use the common Tx free function. This requires
one additional parameter to that function, since iavf sometimes uses
context descriptors which means that we have double the descriptors per
SW ring slot.

net/intel: create common packet reassembly

The code for reassembling a single, multi-mbuf packet from multiple
buffers received from the NIC is duplicated across many drivers. Rather
than having multiple copies of this function, we can create an
"intel/common" directory to hold such functions and consolidate
multiple functions down to a single one for easier maintenance.
