This was just accepted for merging into the spec, so we should probably up the priority of implementing it.

I'm making an attempt at this as I fix Bug 1614041.

Add support for export * as ns from "a"; syntax. This was added in
ECMAScript 2020.
One wrinkle in the implementation is that the parser decides whether to use a
lexical vs indirect binding before module linking. Instead, we reserve a
hidden environment slot called "namespace" for each module that can be
referenced by indirect binding maps as needed.

Update spec references and step numbers to match ES2020. Add TODOs for the
missing steps. There are some editorial changes in latest draft that affect
step numbers, but behaviour is the same for these methods.
