[serialization] Remove skeleton for sharing module decl/type IDs.

Browse Source 
Clang modules have a clever way to share decl and type IDs, by saying
"this range of IDs comes from this other module". Swift modules have to
be resilient, however, and so this is not a viable solution.

We still use 0 as a special ID for null decls and types, when applicable.
