ML-105 Hide providers from the widget tree (#106)

* Added `ServiceProviders` widget

* Added `EnumProviders` widget for enum values

* Moved `ThemeProvider` functionality to `EnumProviders`

* Style

* `EnumProviders` -> `UserPreferencesProvider`

* `ServiceProviders` -> `ServiceProvider`

* Moved `MeteringScreenLayoutProvider` functionality to `UserPreferencesProvider`

* typo

* Removed `InheritedModelAspectListener`

* TODO

* Removed Inherited Generics

* Removed redundant `LightmeterProviders`

* Removed redundant methods from `ServicesProvider`

* `_inheritFrom` -> `_inheritFromEnumsModel`

* Fixed `MeteringScreenLayoutConfig` updates

* Separated `_ThemeModel`

* typo

* `_EnumsModel` -> `_UserPreferencesModel`
