From: John Harrison <John.C.Harrison at 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.

It was also requested to extend this further to submodules in order to
factor out the repeated structure accessing constructs and common
string prefixes. So, add versions for GuC, HuC and GuC CTB as well.

This patch set updates all the gt/uc files to use the new helpers as a
first step. The intention would be to convert all output messages that
have access to a GT structure.

v2: Go back to using lower case names, add more wrapper sets (combined
review feedback). Also, wrap up probe injection and WARN entries.
v3: Split definitions out to separate header files. Tweak some
messages. Wrap a couple more functions. (review feedback from Jani and
Michal W).
