Implement initial support for `A.(B)` syntax, per #989. Specifically, this supports: * `object.(Type.member)` for instance members, * `object.(Interface.member)` for instance and non-instance members, * `object.(Type.(Interface.member))` for instance members, * `Type.(Interface.member)` for non-instance members. Three new AST nodes are introduced: * `CompoundFieldAccessExpression` represents the `A.(B)` syntax. * `MemberName` is a `Value` that represents the result of evaluating an expression such as `Type.member` or `Interface.member` or `Type.(Interface.member)`. * `TypeOfMemberName` is the type of a `MemberName` value. In order to handle members of classes and interfaces which have corresponding declarations and may need substitution into their types, and members of structs which don't have declarations but also don't need substitution, a class `Member` is introduced that can refer to either of these kinds of member.
