HBRT Reserved Mem Trace Buffer implementation.
-Hostboot master Drawer will create TRACEBUF section in the HB Rsvd Mem and HBRT, while booting, gets the TRACEBUF section details and initializes the circual buffer, if available. -If a valid data is present in the buffer, HBRT will create an info log ERRL, otherwise initializes the buffer. -Traces from all components are serialized and stored in the single TRACEBUF in the same format (fsp-binary Trace). When buffer is full, it deletes the oldest entry/entries to store the new ones. -ERRL->collectTrace() works similar to other buffers. -A new test case is added to dump the traces from TRACEBUF.
