[SR-2209] Make a real AccessScope class and use it in access checking.

Browse Source 
1. Add new AccessScope type that just wraps a plain DeclContext.
2. Propagate it into all uses of "ValueDecl::getFormalAccessScope".
3. Turn all operations that combine access scopes into methods on AccessScope.
4. Add the "private" flag to distinguish "private" from "fileprivate"
scope for top-level DeclContext.
