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.

This patch set updates the gt/intel_gt*.c files to use the new helpers
as a first step. The intention would be to convert all output messages
throughout the driver as long as they 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).
Convert all gt/intel_gt*.c but drop the GuC/HuC/CT files as too much
bikeshedding about formatting.
