Optional perfetto annotations (#206)

* Misc tweaks

- C API function print with warning colors
- split region/trace start/stop functions into regions.cpp file

* Config option for disabling perfetto annotations

* Missing checks in roctracer.cpp and sampling.cpp

* Verbose makefile in CI

* run-ci uses -VV

* Fix gcc-7 maybe-uninitialized warning

* Fix push/pop perfetto

- moving perfetto::EventContext was causing errors
