Changed the messages output by Histograming::Sink::Base and RootHistCnv::PersSvc to make using the Sink output a better log file.

Fix a few conversion warnings that show up when compiling the code with
`-Wconversion`. The goal was not to make the code compile without
warnings, but rather reduce the "noise" as much as possible when
compiling client code against Gaudi headers.

patch generated by standalone job

- prefer CommonMessaging when available
- add generic visit to downcast INTupleItem to concrete type and
  invoke the provided callable, and use that to dispatch lambdas
  instead of explicit switch statements with almost identical function
  calls
- use boost::string_ref to avoid copying strings more than strictly
  required
- prefer direct member initialization

- `class NTUPLEINFO` only appears as argument in the declaration of a
  templated function which is not defined

- require public constructor for components
- removed XyzFactory classes
- enabled warning for XyzFactory headers
- some clean up and modernization

- and some minor format tweaking

- remove destructors qualified with 'override = default'
- prefer inheriting constructors

... plus some formatting tweaks,

Adding changes that make it possible to build Gaudi without AIDA and CppUnit. With a reduced set of compiled code of course.
