Pallavi Kadam ce6617a069 net/ice: build on Windows 
- Add Intel ice PMD support on Windows.
- Remove #include sys/ioctl header file as it is not needed.
- Replace x86intrin.h with rte_vect.h to avoid __m_prefetchw conflicting
  types.
- Replace POSIX usleep() API with rte API.
- Add a new macro for the access() API as the original function
  has been deprecated on Windows.
- Add extra cflags '-fno-asynchronous-unwind-tables'
  to avoid MinGW build error:
  Error: invalid register for .seh_savexmm
- Add documentation to support ice PMD on Windows.
  Update the release notes and features list for the same.
