Move UseCaseConfigFactory related files to impl package (LIBRARY_GROUP)

- UseCaseConfigFactory, and ExtendableUseCaseConfigFactory are used in camera2
and testing modules.
- Add related annotations and remove whitelist in lint-baseline.xml

Bug: 146236769
Test: ./gradlew :camera:camera-core:lintDebug &&
      ./gradlew :camera:camera-view:lintDebug &&
      ./gradlew :camera:camera-camera2:lintDebug &&
      ./gradlew :camera:camera-extensions:lintDebug &&
      ./gradlew :camera:camera-lifecycle:lintDebug &&
