7073cf74fe
Introduces the new `ANALYZE_FOR_PRECOMPILE` token. This token can be used to create a virtual provider that will populate the `precompile` fields of components and app modules based on its `useValue`. All components that are referenced in the `useValue` value (either directly or in a nested array or map) will be added to the `precompile` property. closes #9874 related to #9726
