`ConfigurationManager` - It's stupid that it tries to be scoped by `Application.Init`

[tig]

CM is per-process. All the logic in Application.Init should just go away.

I'm working on a fix for this in

• Fixes #4057 - MASSIVE! Fully implements ColorScheme->Scheme + VisualRole + Colors.->SchemeManager.  #4062

This will simplify things and make them deterministic.

As part of this I'm enabling module-initailziation and creating a cache of the hard-coded [SerializableConfigurationProperty] values to prove correctness and enable a "CM is totally disabled" mode.
