ProviderForest class
Represents the dependency injection hierarchy of a view.
This may closely resemble the template structure, as any element that contributes a provider is represented by a ProviderNode; however, any element without a provider is omitted.
Isolating the provider hierarchy like this allows us to optimize it independently from view construction.
Note that since a view may have multiple root nodes, so may it's dependency injection hierarchy, and thus this is technically a forest (consisting of multiple independently rooted trees) in data-structure parlance.
