net/ena: update HAL to the newer version

ena_com is the HAL provided by the vendor and it shouldn't be modified
by the driver developers.

The PMD and platform file was adjusted for the new version of the
ena_com:
    * Do not use deprecated meta descriptor fields
    * Add empty AENQ handler structure with unimplemented handlers
    * Add memzone allocations count to ena_ethdev.c file - it was
      removed from ena_com.c file
    * Add new macros used in new ena_com files
    * Use error code ENA_COM_UNSUPPORTED instead of ENA_COM_PERMISSION
