net/intel: create common mbuf initializer

Across a number of drivers, the same code is used for initializing the
"mbuf_initializer" value inside the rx queue structure for use with the
vector drivers. Since the rx queue structures are (currently) different
across the drivers, we cannot just move a single copy of the function to
a common location. Instead, we create a dedicated function which just
creates the mbuf initializer for a particular port.

In creating this function, we can shorten it vs the original versions by
initializing the mbuf fields as they are defined, rather than
afterwards. We can also remove the use of the barrier and temporary
uintptr_t variable, because the mbuf has been reworked so that
rearm_data is a proper single-element array in a union.

Across ixgbe, i40e, iavf and i40e, we can call this function to
initialize the rxq data, replacing the "*_rxq_vec_setup_default"
functions. Only the i40e was slightly different, having an extra
assignment in it, to set the "sse" flag (even in case of neon and
altivec paths). This assignment was just duplicated to the calling sites
for simplicity and to keep existing behaviour.

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.
