cxl/events: Separate UUID from event structures
The UEFI CXL CPER structure does not include the UUID. Now that the UUID is passed separately to the trace event there is no need to have the UUID in those structures. Move UUID from the event record header to the raw structures. Adjust cxl-test to Create dummy structures for creating test records.
