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.
