Fixes for gcc 13, clang 16 and C++20

Marco Clemencic requested to merge fixes-for-gcc13 into master
  • Hide dangling-reference warnings in selected files
  • Remove unused variables
  • Use || instead of | for booleans

The (spurious) "possibly dangling reference to a temporary" warnings come from the fact that gcc 13 seems not to be able to detect that some_cond.get<json>() returns a reference to the object stored inside an OpaqueDataBlock (it probably gets confused by the DD4hep reimplementation of dynamic_cast invoked in OpaqueData::as()).

Note: based on !448 (merged)
