Design and implement reflection

[RiscadoA]

• Add reflection base type Type.
• Add type kinds PrimitiveType, ObjectType, VariantType, ArrayType and DictionaryType.
• Add utility macros for implement reflection easily.
• Document code througly and add a reflection sample.
• Achieve 100% coverage or near it for the reflection module.
• Automatically set default and move constructors for compiled types.

Implementing new serialization system will be left to the next PR.
