SI-5732 members and derivatives now return Scope

Firstly this unifies the reflection API - now both decls and members
return Scope (not Scope and List[Symbol] as it were before).

Secondly this fixes SI-5732 without having to sort the result of members.
Type.members now returns Scope, a distinguished type, which has the
`sorted` method, which does the required sorting if necessary.

Also removes nonPrivateMembers and nonPrivateDeclarations to keep the API
minimalistic (as can be seen from their implementation in internal.Types
they are just members and decls with bridges and private members removed).
