worker: implement `MessagePort` and `MessageChannel`

Implement `MessagePort` and `MessageChannel` along the lines of
the DOM classes of the same names. `MessagePort`s initially
support transferring only `ArrayBuffer`s.

Thanks to Stephen Belanger for reviewing this change in its
original form, to Benjamin Gruenbaum for reviewing the
added tests in their original form, and to Olivia Hugger
for reviewing the documentation in its original form.
