Add support for telling the debugfs interface the size of the GuC log
dump in advance. Without that, the underlying framework keeps calling
the 'show' function with larger and larger buffer allocations until it
fits. That means reading the log from graphics memory many times - 16
times with the full 18MB log size.
v2: Don't return error codes from size query. Report overflow in the
error dump as well (review feedback from Daniele).

The following interfaces:
i915_wedged
i915_forcewake_user
are dependent on gt values. Put them inside gt/ and drop the
"i915_" prefix name. This would be the new structure:
dri/0/gt
|
+-- forcewake_user
|
\-- reset
For backwards compatibility with existing igt (and the slight
semantic difference between operating on the i915 abi entry
points and the deep gt info):
dri/0
|
+-- i915_wedged
|
\-- i915_forcewake_user
remain at the top level.

We shouldn't be using debugfs_ namespace for this functionality. Rename
debugfs_gt.[ch] to intel_gt_debugfs.[ch] and then make functions,
defines and structs follow suit.
While at it and since we are renaming the header, sort the includes
alphabetically.
