drm/i915: Include the current timeline seqno for debugging execlists

Browse Source 
While this is mainly only useful for ELSP[0], it is definitely useful to
know the current timeline seqno wrt to the queued set of requests for
that port, as this carries additional information above and beyond the
near-defunct global_seqno and global HWSP.
