qcacmn: Add a new trace level for automation of logging

Add a new logging trace level QDF_TRACE_LEVEL_TRACE for
automation scripts to process the logging.

A new logging Infrastructure is to be added where the newly
added logging level QDF_TRACE_LEVEL_TRACE will be used to
log in specific format and these logs will be used by
post processing script to figure out right FA or to figure
the module from where the path deviated. It will help out CST
to figure out the right FA if there are any issues in the driver.
