drm/xe/guc: Increase GuC log sizes in debug builds

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.
