Joe Hoyle a375d93001 REST API: Improve formatting of failed validation errors.
If a validation_callback returns a WP_Error it should give the same response format as if it returned `false`. This makes programmatically reading the validation errors better.

Props bradyvercher for initial patch.
Fixes #35028.
