ice: add support for virtchnl_queue_select.[tx|rx]_queues bitmap

Browse Source 
The VF driver can call VIRTCHNL_OP_[ENABLE|DISABLE]_QUEUES separately
for each queue. Add support for virtchnl_queue_select.[tx|rx]_queues
bitmap which is used to indicate which queues to enable and disable.

Add tracing of VF Tx/Rx per queue enable state to avoid enabling enabled
queues and disabling disabled queues. Add total queues enabled count and
clear ICE_VF_STATE_QS_ENA when count is zero.
