This CL implements the core infrastructure for platform-provided behaviors. `attachInternals()` is updated to accept an optional for behaviors, the `ElementBehavior` base interface is created to represent platform-provided capabilities and a read-only behaviors attribute is added to ElementInternals to track attached behaviors. Behaviors are immutable once attached via `attachInternals()`.
