Refactor the RNTupleWriter internals a bit and reduce some code duplication between the RNTupleWriter and the ROOTWriter
Add getKeys and getValues methods to GenericParameters
Remove the CollectionBranches.h header and move all root related helpers into utilities/RootHelpers.h
ENDRELEASENOTES
In more detail:
Rename the internal RNTupleWriter::CollectionInfo struct to RNTupleWriter::CategoryInfo and group the members that are used to store and write the GenericParameters data into that, such that all data belonging to a category are grouped together
Introduce ParamStorage to more easily refer to a pair of keys and values (vectors). This is done in preparation for another PR that is in the works for addressing #590.
Move some of the typdefs that have been present in the ROOTWriter and the RNTupleWriter into the newly created utilities/RootHelpers.h header
