LibJS: Describe various kinds of "Duration Records"

This is an editorial change in the Temporal spec.

See: https://github.com/tc39/proposal-temporal/commit/983902e

We already had these defined as structs, but now they're properly
defined in the spec (opposed to the previous anonymous records), and we
don't have to make up our own names anymore :^)

Note that while we're usually not including 'record' in the name, in
this case the 'Duration Record' has a name clash with the Duration
object. Additionally, later editorial changes introduce CreateFooRecord
AOs, so let's just go with FooRecord structs here.
