DevTools: make DOMNodeIds a trivial wrapper around WeakIdentifierMap

WeakIdentifierMap is intended for mapping between objects and their identifiers, and
there's currently no reason to generate ids externally, so:

- move id allocation/assignment to WeakIdentifierMap;
- implement Oilpan version of WeakIdentifierMap;
- move DOMNodeIds a trivial wrapper around WeakIdentifierMap;
- get rid of WeakNodeMap header, move the definition to DOMNodeIds.
