Support Tool Intercept API Tables (#165)

* Update include/rocprofiler

- intercept_table.h header
- generic rocprofiler_runtime_library_t
- rocprofiler_internal_thread_library_t is not typedef for rocprofiler_runtime_library_t
- rocprofiler_at_runtime_api_registration

* Update lib/rocprofiler

- minor tweaks to context.cpp
  - check if none context early
  - disallow stop_context when finalizing
- add intercept_table.hpp and intercept_table.cpp
  - implement rocprofiler_at_runtime_api_registration
  - implement notify_runtime_api_registration
- update registration.cpp
  - invoke notify_runtime_api_registration
  - tweak to fini status when invoking client finalizer

* Update lib/rocprofiler/tests

- add tests for intercept table

* Add samples/intercept_table

- demonstrate how to install custom API function wrappers instead of relying on HSA callback tracing

* Update lib/rocprofiler/tests/intercept_table.cpp

- remove _SERVICE from ROCPROFILER_SERVICE_

* Update include/rocprofiler/intercept_table.h

- Update doxygen comments

* Update lib/rocprofiler/intercept_table.cpp

- return error config locked if already initialized

* Update lib/rocprofiler/intercept_table.cpp

- remove unnecessary alias

* Apply suggestions from code review

* Update doxygen comments

- clarify when rocprofiler_at_runtime_api_registration can be invoked

* Use rocprofiler_runtime_library_t for intercept table and internal threading

- remove rocprofiler_intercept_library_t alias to rocprofiler_runtime_library_t
- remove rocprofiler_internal_thread_library_t alias to rocprofiler_runtime_library_t
- move around documentation with regard to rocprofiler_runtime_library_t enumeration
- added some extra doxygen documentation to internal threading functions
