* Update include/rocprofiler

- remove rocprofiler_external_correlation_id_t
- redefine rocprofiler_correlation_id_t to include internal id and external user data
- associate rocprofiler_push_external_correlation_id and rocprofiler_pop_external_correlation_id with a context

* Update include/rocprofiler/rocprofiler.h

- rocprofiler_get_status_name
- rocprofiler_get_status_string

* Update lib/rocprofiler/rocprofiler.cpp

- implement rocprofiler_get_status_name and rocprofiler_get_status_string

* Update lib/rocprofiler/tests/status.cpp

- unit test for status string and name

* Update lib/rocprofiler/tests/registration.cpp

- update to new rocprofiler_correlation_id_t

* Update samples

- update to new rocprofiler_correlation_id_t

* Add lib/rocprofiler/external_correlation.cpp

- placeholder for external correlation push/pop

* Update lib/rocprofiler/hsa/agent_cache.cpp

- slight tweak to when HSA_AMD_AGENT_INFO_NEAREST_CPU is defined

* Update context implementation and hsa.cpp

- get_active_contexts is array of const context pointers
- update hsa_api_impl<Idx>::functor to new rocprofiler_correlation_id_t

* Update include/rocprofiler/fwd.h

- add ROCPROFILER_STATUS_ERROR_INVALID_ARGUMENT
- reorder enum for consistency

* Update include/rocprofiler/external_correlation.h

- doxygen comments
- thread id parameter

* Update include/rocprofiler/rocprofiler.h

- add rocprofiler_get_thread_id function (needed for external corr id)

* Update lib/common/synchronized.hpp

- explicit LockedType
- define all copy/move ctor and assignment
- update rlock/wlock/ulock to support arguments and return values
- Support additional template parameter for special case of synchronized instance which is the mapped type of a sychronized map

* Update lib/rocprofiler/external_correlation.cpp

- implement rocprofiler_{push,pop}_external_correlation_id

* Update lib/rocprofiler/CMakeLists.txt

- external_correlation.hpp

* Update lib/rocprofiler/rocprofiler.cpp

- status string for ROCPROFILER_STATUS_ERROR_INVALID_ARGUMENT
- implement rocprofiler_get_thread_id

* Update lib/rocprofiler/tests (external correlation)

- add external_correlation unit tests

* Update include/rocprofiler/callback_tracing.h

- doxygen comments
- callback invoked in callback tracing has user_data pointer passed to it

* Update samples/api_callback_tracing/client.cpp

- add rocprofiler_user_data_t* to tool_tracing_callback

* Update lib/rocprofiler/tests/registration.cpp

- add rocprofiler_user_data_t* to tool_tracing_callback

* Update lib/rocprofiler/context/context.{hpp,cpp}

- update correlation_tracing_service
  - external_correlation instance
  - rename get_unique_record_id to get_unique_internal_id

* Update lib/tests/common/demangling.cpp

- tweak mangled definitions due to changing function get_unique_record_id to get_unique_internal_id

* Update lib/rocprofiler/hsa/hsa.cpp

- handle updates to external correlation id
- handle updates to callback signature in callback tracing

* Update CMakeLists.txt

- CMAKE_BUILD_TYPE=Coverage defines CODECOV=1

* Update samples/api_callback_tracing/client.cpp
