Response type: Fix deadlock on scenarios with SynchronizationContext for remaining Response.ResourceType

[j82w]

Pull Request Template

Description

This is a continuation of PR #1401 to fix all the remaining types.

The UserResponse.Database is returning UserCore instead of the correct UserInlineCore. To fix this issue the type was converted to inheritance instead of composition.

Composition created a circle reference where UserInlineCore needed UserCore for the actual implementation, but UserCore needed the UserInlineCore for the response creation.

Current model

public abstract User
internal UserCore : User
internal UserInlineCore : User

New model

public abstract User
internal UserCore : User
internal UserInlineCore : UserCore
