[57/69] net/i40e/base: update virtchnl header with advanced features

  Updating the virtchnl header file with new interfaces. The new interfaces
will support the split queue and advanced features. These new features are
initially targeted for APF and CPF driver model. AVF also will enable the
new features in future and use the advanced interfaces.

NACK, this code is not properly stripped and should not be released externally. Additionally, APF is NOT released and is only for Mt Evans and should not be in the code.
