Add base class for sem Struct and StructMember
This CL splits the sem::Struct and sem::StructMember classes into having
a base class and a sem variant. The sem variant contains the
`ast::Declaration` for that sem node. This will allow the base classes
to move into the type hierarchy and keep the sem specific requirements
in the sem folder.
