Upon the G2H Notify-Err-Capture event, parse through the GuC Log Buffer (error-capture-subregion) and generate one or more capture-nodes. A single node represents a single "engine- instance-capture-dump" and contains at least 3 register lists: global, engine-class and engine-instance. An internal link list is maintained to store one or more nodes. Because the link-list node generation happen before the call to devcoredump, duplicate global and engine-class register lists for each engine-instance register dump if we find dependent-engine resets in a engine-capture-group. To avoid dynamically allocate the output nodes during gt reset, pre-allocate a fixed number of empty nodes up front (at the time of ADS registration) that we can consume from or return to an internal cached list of nodes.
