drm/i915: Make GuC log part of the uC error state 

We keep details of GuC and HuC in separate error state struct.
Make GuC log part of it to group all related data together.
Since we are printing uC details at the end, with this change
GuC log will be moved there too.

v2: comment on new placement of the log (Chris)
