We want to save metadata to OffloadBinary in the way that SYCL RT could read without parsing.
For that I implemented utility format/functions in Utility.h (check `llvm/include/llvm/Frontend/Offloading/Utility.h` in this patch). It is used both during generation of OffloadBinary (for writing) and during consuming of data (in SYCL RT).
E.g. llvm::offloading::sycl::forEachSymbol
But this functionality is not part of OffloadBinary, it is just a utility specific for SYCL on top of it.
Offloading/Utility.h includes OffloadBinary.h.
