Exposing more APIs from D/I internals (#2220)

Exposing more internals of D/I, which are required for supporting D/I with more powerful Chisel libraries:

- Exposing IsClone[_]
- Exposing InstantiableClone[_]
- Gated builders for Instance/Definition
- Unsealing Lookupable, with protected accessors for proto and cloned
