net/mlx5: Add satellite PF vport support

Discover satellite PFs from query_esw_functions output and allocate
eswitch vports for them. For each satellite PF, create a vport via the
CREATE_ESW_VPORT command using its vhca_id and allocate it in the
eswitch vport table.

When enabling switchdev mode, the ECPF acting as the eswitch manager
activates each satellite PF with enable_hca, loads its vport and adds
a representor. Since satellite PF devlink ports are registered in a
later patch, guard mlx5_esw_offloads_devlink_port() against vports
with no devlink port to avoid NULL dereference during representor
attach.
