Allow adding extra elements to the developer settings from external modules (#7230)

* Add `ExtraDeveloperOptionsRenderer` to display extra UI components in the developer settings screen. It defaults to not displaying anything, using `NoopExtraDeveloperOptionsRenderer`

* Add `EnterpriseService.overriddenElementWellKnown` method to fetch the current overridden element well known value, if any

* Modify the well known retrievers to use the overridden value if it's there. Also extract the JSON parsing to its own `ElementWellKnownParser` component.

* Bump enterprise repo reference.
