net/ice/base: add functions to get VSI promiscuous mode

Browse Source 
1. ice_get_vsi_promisc - get promiscuous mode of give VSI.
2. ice_get_vsi_vlan_promisc - get VLAN promiscuous mode of given VSI.

PMD may use these APIs to check the real HW status, but not rely on
a software flag when something abnormal.
