Clean up deprecated edm::RefToBase list 1 for RNTuple

[jeongeun]

PR description:

This pull request is the first update to address the opened issue #42737 :

ROOT is eventually deprecating the current TTree data storage in favor of their new RNTuple. The RNTuple is not planned to support dynamic polymorphism. One such use case in our data formats is edm::RefToBase<T> that internally uses dynamic-polymorphism based type erasure. The straightforward migration path is towards edm::Ptr<T>, but there are also many cases where the use of edm::RefToBase<T> could be cleaned up.

This PR covers the first case on the list in the issue #42737.
It contains the set of deprecated edm::RefToBase that only dictionary declaration and/or type aliases and/or commented-out code, otherwise unused case.
All of these can be easily removed without any impact.

This PR was incomplete. All these ::reftobase:: dictionaries should be cleaned up as well. Could you do that?
