[OMPT] Add api_calls_misc.c testcase and rename api_calls.c testcase

The api_calls_misc.c testcase tests the following api calls:

ompt_get_callback()
ompt_get_state()
ompt_enumerate_states()
ompt_enumerate_mutex_impls()
These have not been tested previously.

The api_calls.c testcase has been renamed to api_calls_places.c because it only tests api calls that are related to places.
