This CL adds a new internal service router for the AXTree fixing
feature. This router connects directly to the ScreenAI service and will
be used as a single pipe from the BrowserContextKeyedService tree fixing
Router to the ScreenAI service. This is made internal to the tree_fixing
target, and only the AXTreeFixingServicesRouter can depend on it. In the
future there will be many such internal routers. The top-level Router
provides a public API for any client to perform an AXTree fixing
operation, such as IdentifyMainNode, which is added in this CL.
