System: cleanup paths to use a common class (#29816)

* use OP prefix for logmessage

* cleanup paths too

* cleanup the paths too

* add hw.py to release

* fix those issues

* fix unittests

* fix unittests

* fix unittests

* do swaglog_ipc properly across all the files

* fix that

* fix swaglog in c++

* review suggestions
