net/iavf: build on Windows

Browse Source 
- Enable IAVF PMD build on Windows
- Replace x86intrin.h with rte_vect.h to avoid __m_prefetchw conflicting
  types
- Fix for pointer and integer sign warnings using Clang compiler on
  Windows
- Add extra cflags '-fno-asynchronous-unwind-tables'
  to avoid MinGW build error:
  Error: invalid register for .seh_savexmm

Windows Support
---------------
* IAVF PMD currently is supported only inside Windows guest created on Linux host.
* Physical PCI resources are exposed as virtual functions
into Windows VM using SR-IOV pass-through feature.
* Create a Windows guest on Linux host using KVM hypervisor.
Refer to the steps mentioned in the above section: :ref:`intel_vf_kvm`.
* In the Host machine, download and install the kernel Ethernet driver
for `i40e <https://downloadcenter.intel.com/download/24411>`_
or `ice <https://downloadcenter.intel.com/download/29746>`_.
* For Windows guest, install NetUIO driver
in place of existing built-in (inbox) Virtual Function driver.
* To load NetUIO driver, follow the steps mentioned in `dpdk-kmods repository
<https://git.dpdk.org/dpdk-kmods/tree/windows/netuio/README.rst>`_.
