Support Native AOT compilation of applications against stack

[marcschier]

The goal is to build ConsoleReferenceClient and ConsoleReferenceServer as native and WASM code using NativeAOT.

Work involved.

• Make all libraries trimmable and collect trimmer warnings/errors to understand additional work involved.
• All TypeInfo code using Reflection over object needs be rewritten using generics
• All Clone code using Reflection needs to be rewritten against ICloneable and code must generate ICloneable
• Use Variant for Variant scoped values instead of object.
• Complex type system needs to be rewritten to not use Reflection.Emit
• All serialization code must be generated using source generator
• Provide code generated alternative to encodeable registration via reflection (Assembly enumeration of encodeables)
• Provide code generated alternative to NodeState predefined nodes initialization, Node State creation and children initializationstring initialization
• Configuration via code generation (already possible programmatically, so no priority)
• Support Nodeset (export/import) under Native AOT. #3663
