[RFC 1/8] drm/i915/tracepoints: Tidy request event class

Tvrtko Ursulin

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

At the moment only the global seqno is logged which is not set
until the request is ready for submission.

Add the per-contex seqno and the context hardware id which are
both interesting data points.
