Evgeny Kornev 46e6c161b5 camera: firmware-api: add log and wrapped flag 
Add log level as one of the trace header fields
RCE FW would use it to specify log level error strings
and so KMD could split them between such levels during parsing.

Add wrapped counter to signal the KMD of log wrapping around

* Trace memory consists of three part.

* 1. Trace memory header: This describes the layout of trace memory,

*
* 3. Event memory: This is an array of event entries. This is implemented
* as a ring buffer.
*
* The next index gets updated when new messages are committed to the
* trace memory. The next index points to the entry to be written to
* at next occurrence of the exception or event.
