From: John Harrison <John.C.Harrison@Intel.com>

When trying to analyse bug reports from CI, customers, etc. it can be
difficult to work out exactly what is happening on which GT in a
multi-GT system. So add GT oriented debug/error message wrappers. If
used instead of the drm_ equivalents, you get the same output but with
a GT# prefix on it.

v2: Go back to using lower case names (combined review feedback).
Convert intel_gt.c as a first step.
v3: Add gt_err_ratelimited() as well, undo one conversation that might
not have a GT pointer in some scenarios (review feedback from Michal W).
Split definitions into separate header (review feedback from Jani).
