Add support to drop output dependence to some CP tools

Some jet-related tools missed support to drop the dependencies of their WriteDecorHandles so they can be used properly in AthAnalysis; this MR adds this support. After some discussion in ATLSUSYBGF-672, it was decided to put these updates also in 23.0 (from where they'll be swept to master). To bring some of the tools to the latest status, I had to cherry pick another commit from master first.
