Fixes for gcc 13, clang 16 and C++20
- Fix accumulation functions to work in C++20
- Fix printout of XercesC strings
- Do not build DetDesc dictionary
- Fix implicit capture of this (deprecated in C++20)
- Hide use-after-free warning (backport from LHCb!3875 (merged))
- Remove unused variables
- Hide maybe-uninitialized warning from Vc
The DetDesc dictionary is not really needed and it fails with C++20 because of https://github.com/root-project/root/issues/13001
