Miscellanous AFAR 5 Updates (#891)

* Dispatch table copy/update uses ROCP_TRACE instead of ROCP_INFO

* Update rocprofiler-sdk CMake config

- rocprofiler::rocprofiler is alias to rocprofiler-sdk::rocprofiler-sdk instead of other way around

* Prefer rocprofiler-sdk::rocprofiler-sdk over rocprofiler::rocprofiler

* Fix WITH_UNWIND for glog

- requires a value of "none" instead of boolean now

* Update include/rocprofiler-sdk/registration.h

- explicit struct names to permit forward decl

* Update include/rocprofiler-sdk/cxx/serialization.hpp

- ROCPROFILER_SDK_CEREAL_NAMESPACE_BEGIN and ROCPROFILER_SDK_CEREAL_NAMESPACE_END to enable customized namespace
