[ntuple] RNTuple objects don't appear as variables in the prompt

[jblomer]

Explain what you would like to see improved and how.

We should evaluate what's missing to make them available. It would easy interactive use and be consistent with other ROOT objects (trees, histograms, ...)

ROOT version

master

Installation method

From sources

Operating system

n/a

Additional context

No response

Just trying to add more context here. What is meant in the issue is to add the feature allowing to do the following,

~> root fileContainingRntuple.root
root [0] analyse(myContainedRntuple)

right?

[vepadulano]

I was not aware we wanted to introduce this for RNTuple. Does this mean that also the new file implementation will offer this functionality for all its contained objects?

I think the answer may be "we don't want it", although currently I'm leaning towards adding support. If we drop it, however, we should note down why.
