Integrate Tracy with NR UE & gNB

Browse Source 
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.

How to collect data:
 - Windows hosts: tracy-profiler.exe in link above
 - Linux hosts: Compile tracy-profiler from source

Enabling collection from docker:
 - open port 8086
 - to collect cpu data
    --privileged
    --mount "type=bind,source=/sys/kernel/debug,target=/sys/kernel/debug,readonly"
    --user 0:0
    --pid=host

How to add instrumentation:
 - See examples in this commit or manual in the link above.
