net/ice: 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 to use the
smaller, faster structure.

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 Tx buffer free for AVX-512

AVX-512 code paths for ice and i40e drivers are common, and differ from
the regular post-Tx free function in that the SW ring from which the
buffers are freed does not contain anything other than the mbuf pointer.
Merge these into a common function in intel/common to reduce
duplication.

The queue structures of i40e and ice drivers are virtually identical, so

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.
