starlark: add support for addressing

This change adds support for addressable variables and the unary
prefix operators * and &, which are needed to correctly support
Stargo (see wip-stargo branch), an upcoming extension that enables
Starlark bindings for Go types and variables.

Start reading at the starlark.Variable interface for background.

All new features are behind the -addressing flag.
