REST API: JS Client - Enable connecting to multiple endpoints.

Browse Source 
Enable connecting to multiple wp-api `endpoints`. Calling `wp.api.init` with a new `apiRoot` will parse the new endpoint's schema and store a new set of models and collections. A collection of connected endpoints is stored in `wp.api.endpoints`.

Props lucasstark.
Fixes #39683.
