This commit enables the optional use of Tracy for profiling NR UE & gNB.
See https://github.com/wolfpld/tracy/releases/tag/v0.11.1 for details.

How to compile:
use -DTRACY_ENABLE=ON to enable instrumentation and sampling
For gNB currently only sampling is implemented.

 - Linux hosts: Compile tracy-profiler from source

Enabling collection from docker:
 - open port 8086
 - to collect cpu data
