[Intel-gfx] [RFC 5/7] drm/i915/guc: Update GuC's log-buffer-state access for error capture.

GuC log buffer regions for debug-log-events, crash-dumps and error-state-capture are all a single bo allocation that includes the guc_log_buffer_state structures. Since the error-capture region is accessed with high priority at non- deterministic times (as part of gpu coredump) while the
