rtla/timerlat: Add auto-analysis core

Browse Source 
Currently, timerlat displays a summary of the timerlat tracer results
saving the trace if the system hits a stop condition.

While this represented a huge step forward, the root cause was not
that is accessible to non-expert users.

The auto-analysis fulfill this gap by parsing the trace timerlat runs,
printing an intuitive auto-analysis.
