Integrate RNTuple

[makortel]

Successor of #103.

Now as umbrella issue of the following activities

• NanoAOD RNTuple output module #1118
• Fall 2023 data model planning for RNTuple #1119
• Exploration of data type evolution for RNTuple #1120
• Prototype RNTuple Source and OutputModule #1121
• Explore a plugin system for SoAs
• Re-engineer Source system #1132

Miscellaneous

• Don't throw on ROOT::Experimental RNtuple warning #116
• Deal with the difference in the branch name (https://github.com/cms-sw/cmssw/blob/6636ecebfbf89c6ddff93c31f6c394b125d0c0ae/DataFormats/Provenance/src/BranchDescription.cc#L141-L148)
  • TTree needs a trailing dot ([Tutorial] How to create ROOT Dictionary for a custom class is a stand-alone C++ project root-project/root#13205 (comment))
  • RNTuple forbids (but gives an equivalent behavior out of the box)

Made this issue now a proper umbrella issue, moved the data type evolution tasks into activities tracked in #1122
