refactor ihipPreLaunchKernel phase#1

- Fix calls to HIP_INIT_API to pass all function arguments.
- Change ihipFunction to follow coding convention:
    - leading underscore for member fields,
    - camelCase for member fields.
- move kernel print function inside ihipPreLaunchKernel.
- add HIP_TRACE_API_COLOR, control color of messages.
- add ihipLogStatus wrapper to hipDeviceSynchronize()
