drm/xe/guc: Add GuC log to devcoredump captures
Include the GuC log in devcoredump captures because they can be useful
with debugging certain types of bug.
v2: Fix kerneldoc
v3: Drop module parameter as now using more compact ascii85 encoding
rather than hexdump (although still not compressed) (review feedback
from Matthew B). Rebase onto recent refactoring of devcoredump code.
v4: Don't move the submission snapshot inside the GuC internals
structure 'cos it really doesn't belong there.
