* Update lib/rocprofiler-sdk/context/*
- create correlation_id.{hpp,cpp} and moved implementation into these files instead of in context.{hpp,cpp}
* Update lib/rocprofiler-sdk/thread_trace/att_core.hpp
- fixed header includes
* Update lib/common/utility.hpp (runtime sizeof)
- added compute_runtime_sizeof<T>() function to set the "size" field to be the offset of the "reserved_padding" field if one exists
* Fix to compute_runtime_sizeof
