 #!CommitTicketReference repository="" revision="38806"
 REST API: Include `Vary: Origin` in cors headers

 `vary: origin` is a W3 CORS implementation recommendation(
 https://www.w3.org/TR/cors/#resource-implementation ). It's used by
 default in frameworks such as hapi and Laravel-cors. Overall, it helps
 sites siting behind a cache such as varnish.

 Fixes #38060.
 Props procodewp, pdufour for research.
