[PATCH v4 08/38] net/ice/base: add more APIs in switch module

[Qi Zhang <qi.z.zhang@intel.com>]

Add below APIs in switch module

1. ice_aq_get_vsi_params -  get VSI context info
2. ice_aq_add_update_mir_rule - add/update mirror rule
3. ice_aq_delete_mir_rule - delete mirror rule
4. ice_aq_set_storm_ctrl - set storm control configuration
5. ice_aq_get_storm_ctrl - get storm control configuration

PMD can use these APIs to enable mirror rule and storm control
related features.
