Provides an abstraction for creating the JavaScriptEncoder used in SystemTextConfigurationEditorJsonSerializer (#19849)

* Provides an abstraction for creating the JavaScriptEncoder used in SystemTextConfigurationEditorJsonSerializer.

* Generalised JSON serialization encoder factory to work for all System.Tex.Json serializers.
Added the serializer's name as a parameter to allow for different encodings per serializer if required.

* Fixed tests by removing use of obsolete constructors.

* Removed name parameter and used a generic type instead.
