Enable some QS `multivalentTests` under Ravenwood.

This change is a mechanical adding of the `@EnabledOnRavenwood`
annotation to tests that are known to be passing green under the
Ravenwood environment.

From an earlier change, the default for all `SysuiTestCase` is to
be excluded/ignored when running under Ravenwood, except where a
more-specific annotation overrides it.  (Which is what this change
is doing.)
