[extension] Remove Settings.ModuleInfo and move to service.Host hidden method

[mx-psi]

Description

Moves extension.Settings.ModuleInfo to a service.Host.GetModuleInfo method.

This field probably fits better on extension.Settings or even in component.BuildInfo, but since its contents are a bit in flux per discussions like #12283, I would like to move it here to not stabilize it alongside the rest of extension.

The field is not used in any public code on Github, so I think it won't have a huge impact to remove it in one go, happy to do this in two steps if preferred.

One relevant difference is that this information is no longer available at extension build time, but rather after the Start method is called. Another relevant difference is that this is now available for all component kinds, not just extensions. This could be worked around (we could pass a different host depending on the component kind) but I don't see the use right now.

@djaglowski @dpaasman00 would this be an acceptable solution for you? We may revert back to the current state once we have decided on the ModuleInfo struct contents and structure, but I want to make sure we get it right first.

@mx-psi - responding on behalf of @dpaasman00 and @djaglowski. This is an acceptable change for us - work is currently in flight that depends on this information, but it's not problematic if that work needs to be adjusted based on this change. Simple enough alteration to modify where we are interacting with the information from component initialization to the Start() method.

Nice, glad to hear this :)

Should we have version as well here in the future?

Yes, I think it would make sense to move this to have more structure, but I would rather do this in a separate PR (I would have to start parsing the builder ref and I am worried that this is not trivial)
