Since I accidentally broke the build for some, by putting the pretty
printer for submission inside ifdef HAVE_PROCPS, it's time to move the
whole thing into lib/i915 while fixing this mistake.
Let's also rename the pretty printer and add a doc to it as well as the
section.
Fixes: f6dfe556659f ("lib: Extract helpers for determining submission method")
