[1/N] Agent Counter Collection Implementation (#832)

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.
