net/mlx5: Add management of EC VF vports

Browse source

Add init, load, unload, and cleanup of the EC VF vports. This includes
changes in how eswitch SRIOV is managed. Previous on an embedded CPU
platform the number of VFs provided when enabling the eswitch was always
0, host VFs vports are handled in the eswitch functions change event
handler. Now track the number of EC VFs as well, so they can be handled
properly in the enable/disable flows.

There are only 3 marks available for use in xarrays, all 3 were already
in use for this use case. EC VF vports are in a known range so we can
access them by index instead of marks.
