chore: Refactor global_properties to use the registry pattern

[RobertJacobsonCDC]

This PR refactors global property storage out of the data plugin system and into Context directly. The original hash map based storage is replaced with the "registry pattern" we use for data plugins, entities, and other things elsewhere: set_global_property_value and get_global_property_value now index directly into Context::global_properties using T::id().

I also removed the unused string-based getter mechanism.

Unfortunately, the name-based registration and loading machinery is otherwise left intact, so load_global_properties, add_global_property, and the serialized lookup path continue to work through the existing accessors. The reason is that the load_global_properties uses a string name-based lookup, and it's not clear how to refactor this while also retaining source compatibility with existing code.

On the other hand, if we are willing to break source compatibility, we might as well wait until we have a better idea of the alternative design for global parameters in order to do so, so we don't give client code whiplash.

Client code should remain source compatible for this PR.

This looks good with a couple of small cleanup things. For the record I don't believe the which/that change is justified, but I wouldn't block on it

Alright, alright! Reverted!
