Add guidebook protodata tag: embed prototype values in guidebook text (#27570)

* First clumsy implementation of guidebook protodata

* Support for Properties, format strings

* Better null

* Rename file

* Documentation and some cleanup

* Handle errors better

* Added note about client-side components

* A couple of examples

* DataFields

* Use attributes like a sane person

* Outdated doc

* string.Empty

* No IComponent?

* No casting

* Use EntityManager.ComponentFactory

* Use FrozenDictionary

* Cache tagged component fields

* Iterate components and check if they're tagged
