Lang Hames d5111c292d [ORC] Add support for adding LinkGraphs directly to ObjectLinkingLayer.
This is separate from (but builds on) the support added in ec6b71df70a for
emitting LinkGraphs in the context of an active materialization. This commit
makes LinkGraphs a first-class data structure with features equivalent to
object files within ObjectLinkingLayer.
