Improve static singleton memory safety (#316)

* Update GitHub links

* Update samples/api_buffered_tracing/client.cpp

- check if initialized before forcing initialization

* Add lib/common/static_object.*

- template class for creating a static allocation in the binary which has all the properties of a heap allocated singleton but does not trigger leak sanitizers

* Update include/rocprofiler-sdk/internal_threading.h

- document return values

* Update lib/rocprofiler-sdk/internal_threading.cpp

- return codes from rocprofiler_create_callback_thread and rocprofiler_assign_callback_thread
- use common::static_object for thread-pool object

* Update lib/rocprofiler-sdk/agent.cpp

- use common::static_object to store array of strings and their hashes

* Update lib/rocprofiler-sdk/hsa/code_object.cpp

- use common::static_object to store array of strings and their hashes to ensure strings exist until termination

* Update lib/rocprofiler-sdk/registration.cpp

- use common::static_object to store status and client libraries
- update return values for rocprofiler_set_api_table

* Update lib/rocprofiler-sdk/hsa/hsa.cpp

- check registration::get_fini_status() in hsa_api_impl::functor<Idx>(args...)

* Update lib/rocprofiler-sdk/context/context.cpp

- using common::static_object for correlation id map
