This commit implements a CTF-backend for Zephyr's tracing API.
The CTF-backend itself is split in a middle-layer and a bottom-layer.
- Middle-layer decides the payload in event transactions,
- Bottom-layer implements the IO transport.
A simple POSIX bottom-layer is provided so far.

Change adds CPU stats module for tracing hooks. Module provides
information about percent of CPU usage based on tracing hooks
for threads switching in and out, interrupts enters and exits.
cpu_stats only distinguishes between idle thread, non idle
thread and scheduler.
