REST API: Skip processing fields which are not present in the selected context.

In `WP_REST_Controller::get_fields_for_response()`, exclude fields which are not registered to appear in the request's context.

In conjunction with r45705 this prevents the unnecessary computation of the sample permalink when making a request that is not context=edit.

Props dlh.
Fixes #45605.
