Increase event log size for GuC debug to 16MB, and for general debug to 8MB. This allows for useful debug even if performance-affecting DRM_XE_DEBUG_GUC is not enabled. Without this change, GuC logs gathered by CI are useless for debug due to limited size, which translates to time frame not even able to cover cleanup after test.
