REST API: Site URL setting should not be present on multisite installations.

The `siteurl` setting is registered and made available to the REST API. On a multisite installation, this setting is not configurable from the General Settings screen, but due to the above it is configurable from the REST API.

Props peterwilsoncc.
Fixes #39005.
