Netcore: Migration of Model classes from Umbraco.Infrastructure to Core (#9404)

* Migrating more model, mapping and tree classes

* Migrating files from Mapping dir without Newtonsoft dependency

* Migrating files from PublishedContent and Editors dirs without Newtonsoft dependency + some more of the same kind

* Migrating DataType class without the usage of Newtonsoft.Json and making the corresponding changes to all classes affected

* Combining 3 ContentExtensions files into 1

* Refactoring from migrating ContentExtensions

* Migrating more classes

* Migrating ContentRepositoryExtensions - combining it with existing file in Umbraco.Core

* removing Newtonsoft json dependency & migrating file. Adding partial migration of ConfigurationEditor, so PropertyTagsExtensions can be migrated

* Migrating ContentTagsExtensions, and refactoring from changes in PropertyTagsExtensions

* Changes that should be reverted once ConfigurationEditor class is fully migrated

* VS couldn't find Composing, so build was failing. Removing the using solves the problem

* Handling a single case for deserializing a subset of an input

* Small changes and added tests to JsonNetSerializer
