CI timeout + line-info in releases (#279)

* Update perfetto args.gn.in

- remove enable_perfetto_tools_trace_to_text (unused)

* core timeout implementation

- requires OMNITRACE_CI=ON
- requires OMNITRACE_CI_TIMEOUT=<sec>
- adds pthread_self and std::this_thread::get_id to thread info
- pthread_create_gotcha stores native handles (pthread_self)

* Testing updates

- improve detection of segfault/failures with PASS_REGEX exists
- add OMNITRACE_CI_TIMEOUT env variable to all tests

* Line-info in releases

- e.g. -g1 + more options to minimize size of debug info

* Fix typo in config exit action message

* OMNITRACE_UNLIKELY around debug/verbose messages

* format fixes

* Overflow tests + capability check

* transpose example update

- link to threads library

* roctracer/rocprofiler update

- in ROCm 5.5.0, cannot include rocprofiler.h and roctracer.h in same file due to conflicting enum defs
- Moved HSA tracing setup/shutdown to component::roctracer

* roctracer update

- fix definition of roctracer::setup when disabled

* Update fork example

- detach threads on main PID
- flush io outputs when printing info

* Update overflow tests

- pass regular expressions
- overflow on PERF_COUNT_SW_CPU_CLOCK event

* fork gotcha update

- use getpid() instead of getppid()

* update fork example

- wait on threads calling fork

* timeout update

- wait on timeout thread to launch before proceeding
