We had three `utils::` namespaces, all with different "meaning" (host, device, hsa_utils). We should, when we can, keep "include/Shared" accessible from host and device, thus RefCountTy has been moved to a separate header. `hsa_utils` was introduced to make `utils::` less overloaded. And common functionality was de-duplicated, e.g., `utils::advance` and `utils::advanceVoidPtr` -> `utils:advancePtr`. Type punning now checks for the size of the result to make sure it matches the source type. No functional change was intended.
