Added public API call to setup agent counter collection on a context.
Refactored the return types internally for dispatch counter collection
to use rocprofiler_status_t (allow for more verbose failures to be
surfaced via the API)
Subsequent commits will fill out the sampling functionality for agent
counter collection.
