isRequiredDecl - Check if this is a "required" Decl, which must be seen by consumers of the AST.

Such decls will always be deserialized from the AST file, so we would like this to be as restrictive as possible. Currently the predicate is driven by code generation requirements, if other clients have a different notion of what is "required" then we may have to consider an alternate scheme where clients can iterate over the top-level decls and get information on them, without necessary deserializing them. We could explicitly require such clients to use a separate API call to "realize" the decl. This should be relatively painless since they would presumably only do it for top-level decls.
