sfxge(4): restructure efx_lic to support V3 licensing
Create separate implementations of the efx_lic API for each revision of
the licensing system. All processing of the V1/V2 license partition is
moved to efx_lic, and an implementation of V3 licensing uses the existing
TLV functions with extensions for writing new TLV entries.
