bnxt_en: Add FW trace coredump segments to the coredump

bnxt_en: Add FW trace coredump segments to the coredump

The FW trace coredump segments are very similar to the context
memory segments in the previous patch.  The main difference is
to call HWRM_DBG_LOG_BUFFER_FLUSH to flush the FW data to host
memory and to include an additional record in the coredump that
contains the head and tail information of the trace data.
