Initial commit of a fuzzer for Meshtastic (#5790)

Browse Source 
* Initial commit of a fuzzer for Meshtastic.

* Use a max of 5 for the phone queues

* Only write files to the temp dir

* Limitless queue + fuzzer = lots of ram :)

* Use $PIO_ENV for path to program

* spelling: s/is/to/

* Use loopCanSleep instead of a lock in Router

* realHardware allows full use of a CPU core

* Ignore checkov CKV_DOCKER_2 & CKV_DOCKER_3

* Add Atak seed

* Fix lint issues in build.sh

* Use exception to exit from portduino_main

* Separate build & source files into $WORK & $SRC

* Use an ephemeral port for the API server

* Include CXXFLAGS in the link step

* Read all shared libraries

* Use a separate work directory for each sanitizer
