ice: Refactor VF reset

Currently VF VSI are being reset twice during a PFR or greater. This is
causing reset, specifically resetting all VFs, to take too long. This is
causing various issues with VF drivers not being able to gracefully
handle the VF reset timeout. Fix this by refactoring how VF reset is
handled for the case mentioned previously and for the VFR/VFLR case.

The refactor was done by doing the following:

1. Removing the call to ice_vsi_rebuild_by_type for
   ICE_VSI_VF VSI, which was causing the initial VSI rebuild.

2. Adding functions for pre/post VSI rebuild functions that can be called
   in both the reset all VFs case and reset individual VF case.

3. Adding VSI rebuild functions that are specific for the reset all VFs
   case and adding functions that are specific for the reset individual
   VF case.

4. Calling the pre-rebuild function, then the specific VSI rebuild
   function based on the reset type, and then calling the post-rebuild
   function to handle VF resets.

This patch series makes some assumptions about how VSI are handling by
FW during reset:

1. During a PFR or greater all VSI in FW will be cleared.
2. During a VFR/VFLR the VSI rebuild responsibility is in the hands of
   the PF software.
3. There is code in the ice_reset_all_vfs() case to amortize operations
   if possible. This was left intact.
4. PF software should not be replaying VSI based filters that were added
   other than host configured, PF software configured, or the VF's
   default/LAA MAC. This is the VF drivers job after it has been reset.
