This is a port of prior work from i915 to support fine-grained CPU-GPU
timestamp correlation. Prior work is linked in this issue:
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/384

Mesa and Perfetto are the consumers for this and the issue documents the
need for higher accuracy correlation.
