ice: Support drop action

Currently the drop action is supported only in switchdev mode.
Add support for offloading receive filters with action drop
in ADQ/non-ADQ modes. This is in addition to other actions
such as forwarding to a VSI (ADQ) or a queue (ADQ/non-ADQ).

Also renamed 'ch_vsi' to 'dest_vsi' as it is valid for multiple
actions such as forward to vsi/queue which may/may not create a
channel vsi.
