Refactor(web_feature_consumer): Use ProcessedWebFeaturesData for insertion

This commit refactors the InsertWebFeatures function and its call sites to use the ProcessedWebFeaturesData struct instead of a raw map of features.

In the future, we will need this information to know which features were moved.
