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).
