There is a need to include the GuC log and other large binary objects in core dumps and via dmesg. So add a helper for dumping to a printer function via conversion to ASCII85 encoding. Another issue with dumping such a large buffer is that it can be slow, especially if dumping to dmesg over a serial port. So add a yield to prevent the 'task has been stuck for 120s' kernel hang check feature from firing. v2: Add a prefix to the output string. Fix memory allocation bug. v3: Correct a string size calculation and clean up a define (review feedback from Julia F).
